Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F. (Figure 1)The magnitude of the tension in the string between blocks B and C is T-3.00 N. Assume that each block has mass m 0.400 kg.

Part A

What is the magnitude F of the force?

Part B

What is the tension in the string between blocks A and B?

The horizontal surface on which the objects slide isfrictionless. The acceleration of gravity is 9.8 m/s^2. If F(l) =26 N and F(r) = 3N, find the direction of the resultant force (inrelation to forward, with counterclockwise considered positive).Answer in degrees from the positive x-axis, with counter-clockwisepositive, within the limits of -180 degrees to 180 degrees. Answerin units of degrees.

Picture: thee blocks. F(l) with an arrow pointing toward the 1kg block, then the 1 kg block , then the 9 kg block, and then the 4kg block, and then an arrow of F(r) pointing towards the 4 kgblock.
