Project #85979 - physics

Four charges, q1 = +145 µC, q2 = +46 µC, q3 = −140 µC, and q4 = +21 µC, are fixed at the corners of a 4 m by 5 m rectangle, as illustrated in the figure below. What are the magnitude and the direction of the net force acting on q1? (Assume the x-axis extends from q1 to the right.) magnitude N direction ° counterclockwise from the +x-axis ---------------------------------------- A 6.6-kg box is resting on an inclined surface 39° above the horizontal. Find the normal force exerted by the box on the inclined surface. (Give the magnitude.) N
