Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F_vec The magnitude of the tension in the string between blocks B and C is T = 3.00{\rm N} . Assume that each block has mass m = 0.400{\rm kg} .What is the magnitude F of the force?What is the tension T_AB in the string between block A and block B?
