Statement I: Block A is moving on the horizontal surface towards right under action of force F. All surfaces are smooth. At the instant shown the force exerted by block A on block B is equal to net force on block B.

Statement II: From Newton's third law, the force exerted by block A on B is equal in magnitude to force exerted by block B on A.

Options

A. Statement I is true, statement II is true, Statement II is the correct explanation for statement I.
B. Statemet I is true, Statement II is true , Statement II is NOT the correct explanation for Statement I
C. Statement I is True, Statement II is False.
D. Statement I is False, Statement II is true

Answer

D

Explanation

The FBD of block A is as follows:

The force exerted by B on A is N(normal reaction). The forces acting on A are N (horizontal) and mg(weight downwards). Hence Statement I is false.
