Question

If trolley accelerates horizontally with acceleration a then bob is displaced backward from its initial vertical position.
The angular deflection of the bob in equilibrium is​

Answer 1

Answer:

If trolley accelerates horizontally with acceleration a then bob is displaced backward from its initial vertical position.

The angular deflection of the bob in equilibrium is​ tan^(-1)a/g

Explanation:

Since the bob is in equilibrium,

mgsinθ = ma...........(1)

mgcosθ = mg...............(2)

(1) /(2) we get:

mgsinθ/mgcosθ = ma/mg

tanθ = a/g

θ  = tan^(-1)a/g

Answer 2

Answer:

Answer is Theta=tan^-1 (a/g)
