In the given figure, a body of mass M is held between two massless springs, on a smooth inclined plane. The free ends of the springs are attached to firm supports. If each spring has spring constant k , the frequency of oscillation of given body is:
Options
- A1 2 π 2 k M g sin α
- B1 2 π k M g sin α
- C1 2 π k 2 M
- D1 2 π 2 k M
Correct answer
D. 1 2 π 2 k M
Step-by-step solution
K eq = K 1 + K 2 = K + K = 2 K T = 2 π m K eq = 2 π m 2   K f = 1   T = 1 2 π 2 K   m
