Three equal blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F. The magnitude of the tension in the string between two blocks E and F is T = 3.00N. Suppose that each block has mass m = 0.400 kilogram. Obtain what is the magnitude of the force?
