A body of mass 10 kg has velocities of 10 m/s, 11m/s and 12 m/s at the end of successive seconds. What is force acting on the body?

A

15N

B

20N

C

10N

D

5N

Text Solution

Verified by Experts

The correct Answer is:
C
`because a= (v-u)/(t)`
`therefore "Acceleration"= (11-10)/(1) = (12-11)/(1)= 1m//s^(2)`
`therefore ` The body is moving with a uniform acceleration of 1 `m//s^(2)`
`therefore" Force"= m xx a= 10 xx1= 10N`
