A particle of mass `m` is acted on by two forces of equal magnitude `F` maintaining their orientation relative to the velocity `v` as shown in Fig. The momentum of the particle

Options

A. increases in a
B. decreases in b
C. only the diretion changes in c
D. all are correct

Answer

D

Explanation

a. Resultant force and velocity are parallel so velocity and momentum increases.
Rsultant force and velocity are antiparallel so velocity and momentum decrease.
c. `F` and `v` are perpenducal to each other. So ony direction of momentum change.
