A small ring R is attached to one end of a light inextensible string of length 70 cm. A fixed rough
vertical wire passes through the ring. The other end of the string is attached to a point A on the wire,
vertically above R. A horizontal force of magnitude 5.6N is applied to the point J of the string 30 cm
from A and 40 cm from R. The system is in equilibrium with each of the parts AJ and JR of the string
taut and angle AJR equal to 90
