Given below are two statements:
 Assertion (A): A standing bus suddenly accelerates. If there was no friction between the feet of a passenger and the floor of the bus, the passenger would move back. Reason (R): In the absence of friction, the floor of the bus would slip forward under the feet of the passenger.

 1 (A) is True but (R) is False. 2 (A) is False but (R) is True. 3 Both (A) and (R) are True and (R) is the correct explanation of (A). 4 Both (A) and (R) are True but (R) is not the correct explanation of (A).

Select the correct option based on statements below:
 Assertion (A): Newton's law of action and reaction is a consequence of Newton's law of inertia. Reason (R): Newton's law of inertia implies that any body that is not acted upon by external forces cannot change its state of rest or uniform motion.

 1 (A) is true but (R) is false. 2 (A) is false but (R) is true. 3 Both (A) and (R) are true and (R) is the correct explanation of (A). 4 Both (A) and (R) are true but (R) is not the correct explanation of (A).

Given below are two statements:
 Statement I: (Newton's 1st Law of Motion) Everybody 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. 4 Statement I is False, Statement II is True.

A block of mass $$M$$ lies at rest on a horizontal table.

 Statement I: (Newton's 3rd Law) To every action, there is an equal and opposite reaction. Action and reaction forces act on different bodies and in opposite directions. Statement II: The normal reaction is the reaction force, while the weight is the action.

 1 Statement I is True, Statement II is True and Statement I is the correct reason for Statement II. 2 Statement I is True, Statement II is True and Statement I is not the correct reason for Statement II. 3 Statement I is True, Statement II is False. 4 Statement I is False, Statement II is True.
