a rod of mass m and length ,l is connected to two parallel spring having spring constant of K N/m each. the extension in the spring was fount to be x0 cm. Now the springs are joined by a battery which suppy a current of i A in a transverse magnetic field of B tesla.
the extension now is x cm (x0>x). if the max. magnetic force acting on the rod is 4N and the wt. of rod is 9N. What will be the fractional extension in the spring?
