The minimum force required to move a body up an inclined plane is two times the minimum force required to prevent it from sliding down the plane. If co-efficient of friction between the body and inclined plane is (1)/(sqrt(3)), the angle of inclined plane is

The minimum force required to move a body up an inclined plane is two

1.	The minimum force required to move a body up an inclined plane is two times the minimum force required to prevent it from sliding down the plane. If co-efficient of friction between the body and inclined plane is (1)/(sqrt(3)), the angle of inclined plane is
