Block A as shown in Fig weighs `2.0 N` and block B weighs `6.0 N` The coefficient of kinetic friction between all surface is `0.25` Find the magnitude of the horizontal force necessary to drag block B to the left at constant speed if A and B are connected by a light , flexible cord passing around a fixed, frictionless pulley.

Block A, as shown in Fig. 7.303 weighs 2.0 N and block B weighs 6.0 N. The coefficient of kinetic friction between all surfaces is 0.25. Find the magnitude of the horizontal force necessary
