A rod of length 56.0 cm and mass 1.40 kg is suspended by two strings which are 42.0 cm long, one at each end of the rod.
The string on side B is cut. Find the magnitude of the initial acceleration of end B.
The string on side B is retied and now has only half the length of the string on side A.
Find the magnitude of the initial acceleration of the end B when the string is cut.

The string on side B is retied and now has only half the length of the string on side A. & Find the magnitude of the initial acceleration of the end B when the string is cut.
When the string is cut rod rotates about other end. Let's take moment equation about that end:
