Question

A body is acted upon by two forces each of magnitude F, but in opposite directions, state the effect of forces if the forces act along same line of action *


Resultant force equal to zero

Moment of force equal to zero

There will be no motion

All the above

​

Answer 1

Answer:

there will be no motion.

Explanation:

Here, we are applying two force in same magnitude but in opposite that is one is F and -F. Hence resultant force is F+(−F)=0.

Hence, resultant force is zero. Here perpendicular distance is same for both the forces.

Hence, if we calculate r×F cross product. We get the same magnitude of moments but opposite in direction as force are of opposite in direction. Hence moments are also zeroes. Without any resultant and moment there will be no motion.
