Physics confusion please help! A heavy steel ball is hung from a cord to make a pendulum.?

A heavy steel ball is hung from a cord to make a pendulum. The ball is pulled to the side so that the cord makes a 5 ∘ angle with the vertical. Holding the ball in place takes a force of 40 N . If the ball is pulled farther to the side so that the cord makes a 8 ∘ angle, what force is required to hold the ball?

I will award the Best answer. F=__ ___

40 = m*g*sin(5°)
m*g = 40/sin(5°)

New force = mg*sin(8°) = 40 / sin(5°) * sin(8°) = 63.8 N
