Question

a small sphere is suspended by a string from the ceiling of a car. if the car begins to move with a constant acceleration a, the indication of the string to the vertical is??

Answer 1

the indication of the string to the vertical is backward

Answer 2

I think it's inclination not indication..

the string moves backward with and angle = tan(-1) (a/g)...

Or, tangent of the angle is the ratio of constant acceleration 'a' and 'g'

I hope it helps.
