Question

A block of mass 2 kg slides on incline plane with inclination 30 degree and coefficient of friction under 3 by 2 what is the what force should be applied on the block along inclined plane so that it moves without downloads

Answer 1

Answer- F = 20.77 N

Explanation-

# Given-

m = 2 kg

μ = √(3/2) = 1.225

θ = 30 °

# Solution-

For acceleration to be zero, force should be provided to balance frictional force.

F = μmgcosθ

F = 1.225 × 2 × 9.8 × cos30°

F = 20.77 N

Force of 20.77 N should be applied to get zero acceleration.
