Two blocks of masses m and M,(Mm) are placed on a frictionless table as shown in figure. A massless spring with spring constant k is attached with the lower block. If the system is slightly displaced and released, then ( \mu= coefficient of friction between the two blocks) A. The time period of small oscillation of the two blocks is T=2 \pi \sqrt{\frac{(m+M)}{k}} B. The acceleration of the blocks is a=-\frac{k x}{M+m} ( x= displacement of the blocks from the mean position) C . The magnitude of the frictional force on the upper block is \frac{m \mu|x|}{M+m} D. The maximum amplitude of the upper block, if it does not slip, is \frac{\mu(M+m) g}{k} E. Maximum frictional force can be \mu(M+m) g Choose the correct answer from the options given below: [3 Apr 2025 Shift 1]
