A block of mass 2 kg slides on an inclined plane which makes an angle of 30° with the horizontal. The coefficient of friction between the block and the surface is 
. The force along the plane that needs to be applied to the block so that it moves up without any acceleration is (take g = 10ms -2 )
Text Solution
Verified by ExpertsThe correct answer is:
D
25 N
For acceleration to be zero, the net force should be zero.
F = mg sin 
+ 
mg cos
