Question

in a system of units of mass 10 kg unit of length is 5 m and unit of time is 1 second what will be unit of force
25N
50N
0.5N
2500N​

Answer 1

Answer:

Explanation:

(D) 5 Newtons

Given :

Mass of the body = 10 kg

Acceleration of the body with which it is moving = 0.5 m/s²

To find :

Force acting on the body

Force = Mass×Acceleration

Force = 10×0.5

Force = 5 Newtons

A force of 5 Newtons on a body of mass 10kg produces it an acceleration of 0.5 m/s²

Hence option (D) is correct

Extra :

Force can be rewritten as m(v-u) /t, because a = (v-u) /t
