Question

a box of mass 50 gram is kept on a horizontal force when it is published by a horizontal force H it moves with a constant velocity. if it is pushed by a 1.5 H it moves with an acceleration of 0.1 m/s^2 find the value of H

Answer 1

Given,

mass of the box = 50/1000= 0.05kg

If force is H ,it moves with constant velocity .

A/q

Force =mass *acceleration

=> 1.5 H = 0.05*0.1

=> H = 0.005/1.5 N = 0.0033 N

Thus , we get applied force H = 0.0033N

that is negligible.

But in 2nd case, it is 1.5 times, then after force seems to be applied
