Question

A constant force (F) is applied on a stationary particle of mass m. the velocity attained by the particle in a certain displacement will be proportional to?

Answer 1

It will be zero when constant force is applied

Answer 2

Answer:

1/$\sqrt{m}$

Solution:

F = ma

∴ a = F/ m

Moreover

v² = u² + 2as

∴ v² = 2 × F/m × s

∴ v = √2×F/m×s

∴ v ∝ 1/√m
