Question

The resurtant force of two equall parallel force acting in opposite direction in the same line of action is

Answer 1

Explanation:

Explanation: Couple: A pair of two equal and unlike parallel forces (i.e. forces equal in magnitude, with lines of action parallel to each other and acting in opposite directions) is known as a couple.

Answer 2

Answer:

zero

Explanation:

Physics question are easy peasy if you visualize them. (there's a drawing enclosed below to help u with that ;) )

Say, the forces in the same line of action is A and B. A is equal to B in terms of magnitude. But A and B have opposite directions. Hence, A equals to the  negative direction of B and vice versa. So, A and B will cancel each other out because the have the same magnitude but opposite directions.
