Explanation:
It is given that,
The mass of bob, m = 77 kg
Length of the string, L = 10 m
Angle made by the string with the vertical,
(a) Let T is the force exerted by the string on the pendulum. At equilibrium,
T = 755.63 N
The horizontal component of the force is given by,
The vertical component of the force is given by,
(b) Let a is the radial acceleration of the bob. It can be calculated as :
Hence, this is the required solution.
