Question

A block.Of mass 4 kg is placed on a rough inclined surface as shown . The minimum force f which is parallel to inclined to keep the block at rest is....(g=10m/s^2)

Answer 1

Answer:

Explanation:

as we know that

F=MA

MASS= 4KG

ACCELERATION= 10m/S^2

MA= 4*10= 40 NEWTON

40 NEWTON MEANS THAT ATLEAST 40 NEWTON FORCE WOULD BE NEEDED TO MOVE THE OBJECT.

WE CAN ALSO SAY THAT THE FRICTIONAL FORCE IS 40 NEWTON
