Assignment:
Two hanging balls, each with a mass of 10g, have equal charges. One ball is hung by an insulated thread. Another ball held by an insulated rod. When it is brought horizontally towards the hanging ball within .12m of the hanging ball, the suspended ball is deflected (deflection due to like charges on both balls) until the thread creates a 30 degree angle with the vertical while its distance is still .12m from the ball held with an insulated rod. At this angle, the forces are balanced.
A) Draw a force diagram for the balls
B) Calculate Force due to gravity F_gravity
C) Calculate electric force F_electric
D) Calculate charge on each ball.
Provide complete and step by step solution for the question and show calculations and use formulas.
