Answer 1

QUESTION

A body of mass 2 kg is moving over a

perfectly smooth surface with a

uniform velocity of 5 metre per

second. The external force acting on

the body is

a 10N

b 10dyne

c Zero

d Cannot say

ANSWER

AS THE BODY MOVES WITH AN UNIFORM VELOCITY, SO ACCELERATION IS 0 m/s²

SINCE ACCELERATION IS 0

SO FORCE APPLIED=MASS×ACCELERATION

=2×0=0 N

SO OPTION

✔️C)ZERO
