A horizontal force is used to push an object of mass m up an inclined plane. The angle between the plane and the horizontal is $\theta$. The normal reaction force of the plane acting on the mass m is
A) mg cos $\theta$+ F cos $\theta$
B) mg cos $\theta$
C) mg cos $\theta$ + F sin $\theta$
D) mg cos $\theta$- F cos $\theta$
E) impossible to determine because the coefficient of friction is not given.
