As shown in figure, the block of 2 kg at one end and the other of 3 kg at the other end of a light string are connected. It the system remains stationary find the magnitude and direction of the frictional force,(g=10ms2)
- 20 N, downward on slope
- 20 N, upward on slope
- 10 N, Downward an slope
- 10 N, upward on slope
The correct answer is: 20 N, downward on slope
