A right triangle has sides of 30, 40 and 50 cm. A charge of -10 x 10-6 C is placed at the right angle; a charge of + 10 x 10-6C at the smaller acute angle and a charge of + 5.0x10-6 C at the larger acute angle. Draw a diagram showing the individual forces and the resultant force acting on the charge at the right angle. Find the force on the charge at the right angle, and find the angle this force makes with one of the legs.
