Question

Suppose two forces act on an object of finite extent, such as a baseball. Are these two forces equivalent if they are represented by equal vectors? Suppose a particle travels a distance d = Deltax rectilinearly along the x-axis. Suppose further that z act on the particle throughout the displacement d. What can we say about the wc done by force F_1? (a) F_1 does some work on the particle during the displacement. (b) F_1 does no work on the particle during the displacement. The magnitude of the normal force acting on particle is always equal to the magnitude of the particle weight.

Explanation / Answer

Yes the two forces will be equivalent because vector represent the magnitude and direction of the quantity and if both the quantities are equal the force will be equivalent
