A positive charge of +q1 is located 5.22 m to the left of a negative charge -q2. The charges have different magnitudes. On the line through the charges, the net electric field is zero at a spot 2.55 m to the right of the negative charge. On this line there are also two spots where the potential...

that is the exact question that the professor gave and i am assuming that the pendulum is in motion. this is the picture that seemed to relate to this problem. i hope that you can help!

A student wishes to figure out the starting angle of the pendulum bob in this experiment. The 50 cm mark is directly below the point of support of the pendulum and the distance from the point of support to the center of the bob is 120 cm. The student measures the diameter of the pendulum bob to...
