Question

The relation F=ma cannot be deduced from Newton's second law,if
(a) force depends on time
(b) momentum depends on time
(c) acceleration depends on time
(d) mass depends on time​

Answer 1

Answer: if mass depends on time.

Explanation: because even though the acceleration is constant we can never deduce force if mass will change after a certain amount of time.

Answer 2

ANSWER:

Option d) mass depends on time

EXPLANATION:

     As the formula state that the product of mass and acceleration is called Force, now as we all know that the acceleration is or can be dependent on time due to being vector quantity but mass being a scalar quantity.

    So the force can be deduced even, if the acceleration is volatile or dependent on time but if the mass changes every-time, then deduction of force becomes difficult. Therefore, force can’t be deduced if the mass depends on time.
