Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Why is sliding friction always slightly smaller in magnitude than static friction between the same two surfaces?

सर्पी घर्षण का मान स्थैतिक घर्षण से सदैव थोड़ा कम क्यों होता है?

Because objects become lighter when movingक्योंकि वस्तुएँ हिलने पर हल्की हो जाती हैं

Because gravity decreases during slidingक्योंकि फिसलने के दौरान गुरुत्वाकर्षण कम हो जाता है

When an object starts sliding, the contact points on its surface do not get sufficient time to lock deeply into the contact points of the floorजब कोई वस्तु फिसलने लगती है, तो उसकी सतह पर संपर्क बिंदुओं को फर्श के संपर्क बिंदुओं में गहराई से लॉक होने के लिए पर्याप्त समय नहीं मिलता है

Because air lifts the sliding objectक्योंकि हवा फिसलती हुई वस्तु को उठा लेती है

Correct Answer: Option C

Explanation:

Static friction requires breaking fully established microscopic interlocking. Once sliding begins, moving irregularities glide over surface ridges without settling into deep interlocking pockets, reducing friction.

Why does walking on a smooth marble floor coated with spilled soap water or oil become extraordinarily difficult and hazardous?

साबुन के पानी या तेल से गीले फर्श पर चलना अत्यधिक कठिन क्यों हो जाता है?

Soap water creates a slippery film that fills surface irregularities, drastically reducing the frictional grip between shoes and floor needed for propulsionसाबुन का पानी एक फिसलन भरी फिल्म बनाता है जो सतह की अनियमितताओं को भर देता है, जिससे जूते और फर्श के बीच प्रणोदन के लिए आवश्यक घर्षण पकड़ काफी कम हो जाती है।

Soap water increases gravityसाबुन का पानी गुरुत्वाकर्षण बढ़ाता है

Soap water attracts shoes upwardसाबुन का पानी जूतों को ऊपर की ओर आकर्षित करता है

Water increases static friction tenfoldपानी स्थैतिक घर्षण को दस गुना बढ़ा देता है

Correct Answer: Option A

Explanation:

Walking requires backwards foot thrust generating forward frictional reaction ($F = ma$). Soap or oil creates a thin lubricating layer separating sole from floor, eliminating interlocking and causing slippage.

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in high school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, CUET, and Foundation JEE/NEET.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
