Question

A block of mass m slides down a frictionless slope inclined at an angle θ to the horizontal. The magnitude of the acceleration of the block is observed to be a. From this observation you can conclude that the magnitude of the local acceleration due to gravity is:

TestHub · Accepted Answer

On a frictionless slope the weight component along the plane is mg sin θ , so ma = mg sin θ ⇒ a = g sin θ ⇒ g = sin θ a ​ Correct option: (C).
