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
Explanation:
Laws of Motion

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

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 ?

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
