Laws of Motion

270117 While walking on ice one should take small steps to avoid slipping. This is because smaller steps ensure

1 larger friction
2 smaller friction
3 larger normal force
4 smaller normal force
Laws of Motion

270118 In order to stop a car in shortest distance on a horizontal road, one should

1 apply the brakes very hard so that the wheels stop rotating
2 apply the brakes hard enough to just prevent slipping
3 pump the brakes (press and release)
4 shut the engine off and not apply brakes
Laws of Motion

270119 A body rests on a rough horizontal plane. A force is applied to the body directed towards the plane at an angle ? with the vertical. The body can be moved along the plane

1 only if ? is greater than the angle of friction
2 only if ? is lesser than the angle of friction
3 only if ? is equal to the angle of friction
4 for all values of ?
Laws of Motion

270120 A lift is moving down with an acceleration equal to the acceleration due to gravity. A body of mass \(M\) kept on the floor of the lift is pulled horizontally. If the coefficient of friction is \(\mu\), then the frictional resistance offered by the body is

1 \(\mu_{\mathrm{k}} \mathrm{Mg}\)
2 \(\mathrm{Mg}\)
3 Zero
4 \(\mu_{\mathrm{k}} \mathrm{Mg}^{2}\)
