A flatbed truck goes around a curve of radius R with speed V.There is a box on the truck of M kg mass.Which statement is correct concerning the net horizontal force on the box,if the box does not slide? A)It is MV²/R outward from the center of the curve. B)It is zero. C)It is MV²/R inward towards the center of the curve. D)It is MgR outward from the center of the curve. E)It is MgR inward towards the center of the curve.

The net horizontal force on the box is in the direction of the centripetal force required to keep it moving in a circular path. This force is given by F = Mv^2/R, where M is the mass of the box, v is the speed of the truck, and R is the radius of the curve. Since the box is not sliding, the force of friction between the box and the truck is also in this direction. Therefore, the net horizontal force on the box is inward towards the center of the curve. Choice C is the only option that reflects this.
