-Two masses are connected by a string which goes over an ideal pulley as shown in Figure 6-12. Block A has a mass of 3.00 kg and can slide along a rough plane inclined 30.0° to the horizontal. The coefficient of static friction between block A and the plane is 0.400. Block B has a mass of 2.77 kg. What is the tension in the string?
A) 22.0 N
B) 22.7 N
C) 26.1 N
D) 24.5 N
E) 27.3 N

Question

Quizplus · Accepted Answer

The tension in the string can be calculated using the forces acting on both blocks, considering the gravitational force, frictional force, and the incline angle. The correct calculation gives a tension of 26.1 N.
