MHT CET 2023 Physics question
Under the influence of force 'F' the body oscillates with a period 'T' and due to another force 'F' body oscillates with period 'T'. If both forces acts simultaneously then the resultant period is (consider displacement is same in all three cases)
Answer: (B)
Solution
With the same displacement , the restoring forces are and ; when both act together the net force is , so the effective force constant is . From we have , so
