Solutions for Conceptual questions of Newton's law

1.sol:- (d) A body acted uopn by a certain force produces acceleration i.e. it undergoes change in it's velocity. hence choice (d) is correct
2. sol:- (a)
3. sol:-(d)
4. sol:- (b)
since velocity of block when it reaches the ground is given by v=(2gh)1/2 the correct choice will be (b).
5. Solution:A,C
6. sol:- (a)
7. Solution :(c)
8. Solution:(c)
