Question

24. In what position, the rod must be set so that if
displaced a little from that position, it begins simple
harmonic oscillations about the axis?
Pls answer all 3
I will make brainliest​

Answer 1

Explanation:

For the SHM ,first described the mean position and here it is the position where net force due to electric field is zero., that is stable equilibrium.their is translatory equilibrium.

but the vertical axis passing through a point at L/4 distance from its end so that torque acts on it is different.

the position where the rod execute SHM must have force acting towards the mean position.
