1) Three forces are exerted on an object placed on a tilted floor in the figure below. The forces are measured in Newtons (N). Assuming that forces are vectors. a) What is the component of the net force r F net = r F 1 + r F 2 + r F 3 parallel to the floor? b) What is the component of r F net perpendicular to the floor? c) What are the magnitude and direction of r F net ? 2) The figure below shows four electric charges located on

Unformatted text preview: the corners of a rectangle. Like charges repel each other while opposite charges attract. Charge B exerts a repulsive charge (directly away B) on charge A of 3.0 N. Charge C exerts an attractive force (directly toward C) on charge A of 6.0 N. Finally charge D exerts an attractive force of 2.0 N on A. Assuming the forces are vectors, what are the magnitude and direction of the net force on A?...
