Solve the problem.
-The force acting on a pendulum to bring it to its perpendicular resting point is called the restoring force. The restoring force F, in Newtons, acting on a string pendulum is given by the formula
F = mg sinθ
Where m is the mass in kilograms of the pendulum's bob, g =9.8 meters per second per second is the acceleration
Due to gravity, and θ is angle at which the pendulum is displaced from the perpendicular. What is the value of
The restoring force when m = 0.7 kilogram and θ = 45°? If necessary, round the answer to the nearest tenth of a
Newton.
A) 4.7 N
B) 4.6 N
C) 5.8 N
D) 4.9 N

The restoring force F is calculated using the formula F = mg sinθ. Substituting m = 0.7 kg, g = 9.8 m/s², and θ = 45°, we get F = 0.7 * 9.8 * sin(45°). Since sin(45°) = √2/2 ≈ 0.7071, F ≈ 0.7 * 9.8 * 0.7071 ≈ 4.9 N.
