Question

14. Multiple Choice. A toy airplane, connected to the ceiling by a thin massless cord travels is a circle at a constant speed. The net force acting on the airplane points in which direction? Circle the correct answer a In the direction of motion (tangent to the path). b. Opposite the direction of motion (tangent to the path). c. Directly toward the center of the circular path. d Directly away from the center of the circular path. C. Along the cord, toward the ceiling. f. Along the cord, away from the ceiling.

Answer 1

Here,

as the airplane is moving in the circle at constant speed

the tangential acceleration is Zero

the acceleration will only be centripetal acceleration

the direction of net acceleration is towards the center of the circle

hence , the net force is also towards the center of circle

the correct option is

C) Directly toward the center of the circular path
