Problem
Two identical boxes are acted upon by the same horizontal magnitude of force F at the same angle θ to the horizontal. In case I the force is a pull (acting upward at θ), while in case II it is a push (acting downward at θ). The coefficient of static friction for both is μs. Which statement is correct regarding the ease of starting motion?
(a) Both require the same minimum magnitude to start motion.
(b) The push starts motion more easily than the pull.
(c) The pull starts motion more easily than the push.
(d) The minimum force required depends on the numerical value of μs.
