A constant force \( F \) is applied on a spring block system as shown in figure-5.137. The mass of the block is \( m \) and spring
\( \mathrm{P} \) constant is \( k \). The block is placed over a smooth surface. Initially

W the spring was unstretched. Choose the correct alternative(s):
(A) The block will execute SHM
(B) Amplitude of oscillation is \( \frac{F}{2 k} \)
(C) Time period of oscillation is \( 2 \pi \sqrt{\frac{m}{k}} \)
(D) The maximum speed of block is \( \sqrt{\frac{2 F x-k x^{2}}{m}} \)
