A 10 kg block is on a rough 37° inclined plane with μ = 0.5. A force F is applied up the incline. Which statements are correct?

Select all that apply

• Option A

  For F = 30 N, acceleration is zero and friction is 30 N.

• Option B

  For F = 60 N, acceleration is zero and friction is 60 N.

• Option C

  For F = 90 N, acceleration is zero and friction is 30 N.

• Option D

  For F = 120 N, acceleration is 2 m s⁻² and friction is 40 N.
