The goal of this traction system is to have directly in line with the fractured femur, at an angle of 20.0 above the horizontal. Part A Find the angle required to produce this alignment of . (Assume the pulleys are ideal.) Part B
Find the magnitude of the force, that is applied to the femur in this case.
A diverging lens (f = -12 cm) is located 20 cm to the left of a converging lens (f = 35.0 cm). A 3.00 cm tall object stands to the left of the diverging lens, exactly at its focal point.
A point charge +6.7 uC is placed at the origin, and a second charge -3.6 uC is placed in the X - Y plane at (0.40 m , 0.55 m ). Where should a third charge be placed in the plane so that the net force acting on it is zero? Express your answers usi..
