- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Sphere is said to be small therefore we can ignore its moment of inertia. The net downward force acting on the sphere will be, F=mg-Eq⇒F=mg-Eqm From the above expression, we can say that the effective acceleration due to gravity will be g'=g-Eqm. The time period of the…
