Question

A body is acted upon by two forces each of magnitude F,but in opposite direction.State the effect of the forces.

(a) if the forces act at two different point of the body at a separation r.​

Answer 1

Answer:

hey mate

Explanation:

ANSWER

Here we apply two forces of same magnitude but opposite in direction.Hence we have F and - F which makes resultant force as zero.

Moment of force for F is r×F. For force F it has distance r therefore it has moment rF and same with force -F.Hence moment of force is rF.

The forces tend to rotate the body about the mid-point between the two forces.
