Question

An object is moving on a plane surface uniform
velocity 10 ms-7 in presence of a force 10 N.
The frictional force between the object and the
surface is
(1) IN
(2) -10 N
(3) 10 N
(4) 100 N​

Answer 1

Answer:

2

Explanation:

because body is in uniform motion

there is no change in velocity,means no acceleration

so,net force is zero.

10N+X=0

X=-10N
