Question

A simple pendulum is oscillating without damping . when the displacement of bob is less than maximum . the net force vector on the bob

Answer 1

Answer:

Net force make some angle with the tangential direction of the motion of the pendulum

Explanation:

As we know that pendulum is oscillating between its maximum and mean position

So at the given instant it is not at rest and hence we can say

net centripetal force on it is given as

$F_c = \frac{mv^2}{L}$

$T - mg cos\theta = \frac{mv^2}{L}$

so this centripetal force is towards the hinge point

Again we can see that it has one component of weight along the tangential direction

So tangential force on it is given as

$F_t = mg sin\theta$

so net force on the pendulum must be between the two forces

so it will make some angle with the tangential direction of the motion of the pendulum
