Answer:
Explanation:
Newton's second law of motion states that the rate of change of momentum is proportional to the applied force and it takes place in the direction of the force
I.e
F ∝ rate of change of momentum
Momentum is given as p =mv
F ∝ (mv-mu) / t
Let k be constant of proportion
F =k (mv-mu)/t
F= km(v-u)/t
We know that,
a = ∆V/t = (v-u)/t
Then,
F = kma
The unit of force is chosen so that k=1.
Then, F=ma
So, rearranging this will give as
a = F/m
If we assume that F is constant
Then, a ∝ 1/m
So, acceleration is inversely proportional to mass
The right option is b.
