A stretched string is fixed at both its ends. Three possible wavelengths of stationary wave patterns that can be set up in the string are 90 cm, 60 cm and 45 cm. the length of the string may be

A block M hangs vertically at the bottom end of a uniform rope of constant mass per unit length. The top end of the rope is attached to a fixed rigid support at O. A transverse wave pulse (Pulse 1) of wavelength lamda_(0) is produced at point O on the rope. The pulse takes time T_(OA) to reach point A. If the wave pulse of wavelength lamda_(0) is produced at point A (Pulse 2) without disturbing the position of M it takes time T_(AO) to reach point O. Which of the following options is/are correct?

Two masses of 10kg and 5kg are suspended from a rigid support as shown in figure. The system is pulled down with a force of 150N attached to the lower mass. The string attached to the support breaks and the system accelerates downwards In case the force continues to act. what will be the tension acting between the two masses ? .
