1. fly up
2. slip along the surface
3. fly along a tangent to the earth’s surface
4. remain standing

Given below are two statements:
Statement I: (Newton's 1st Law of Motion) Every body continues in its state of rest or of uniform motion in a straight line except in so far as it be compelled by an externally impressed force to act otherwise.
Statement II:  It is observed that when a car brakes suddenly, the passengers are thrown forward.
 
1. Statement I is true, Statement II is true, and Statement I is the correct explanation of Statement II.
2. Statement I is true, Statement II is true, and Statement I is not the correct explanation of Statement II.
3. Statement I is true, Statement II is false.

In the figure given below, a wooden block of mass \(2\) kg rests on a soft horizontal floor. When an iron cylinder of mass \(25\) kg is placed on top of the block, the floor yields steadily and the block and the cylinder together go down with an acceleration of \(0.1~\mathrm{m/s^2}\). What is the force of the block on the floor after the floor yields? (Take \(g=10~\mathrm{m/s^2}\).)
     

1. \(270\) N upward
2. \(267.3\) N downward
3. \(20\) N downward
4. \(267.3\) N upward

Two objects \(A\) and \(B\) are thrown upward simultaneously with the same speed. The mass of \(A\) is greater than the mass of \(B\). Suppose the air exerts a constant and equal force of resistance on the two bodies.

1. the two bodies will reach the same height.
2. \(A\) will go higher than \(B\).
3. \(B\) will go higher than \(A\).
4. any of the above three may happen depending on the speed with which the objects are thrown.
