Question

A body of mass 10 kg is moving with an acceleration of 0.5 ms-2. The force exerted on the body is ________



A
10N

B
50N

C
0.5N

D
5N

​

Answer 1

Answer:

D. 5N

Explanation:

force = mass × acceleration

= 10 × 0.5

= 5 N

Answer 2

Answer:

(D) 5 Newtons

Explanation:

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
