MHT CET Physics question
A body is oscillating vertical about its mean position with period s. If its maximum and minimum heights above the surface of the ground are 2 m and 1.5 m, then the speed at midway between mean and extreme position will be
Answer: (B)
Solution
A = (2 - 1.5)/2 = 0.25 m and = 2 /; at x = A/2, v = = (/2) A =
