उत्तर
The force is maximum at a time `(3T)/4`.
Explanation:
Express the relation of force. F = ma
Here, m is the mass of the particle.
a is the acceleration.
Since acceleration is maximum at extreme positions, Force is also maximum at extreme positions. At time `(3T)/4` particle is at extreme position. Therefore, at `(3T)/4` force is maximum.
