A 10N metre stick rest on pivot of 25 cm, and a boy hold the other end, exerting an upward force. the stick is loaded with 75N at 5cm, 27.5N at 5cm and 12.5N at 90 cm. calculate how much force the boy exert on sticks

Agalvanometer has an internal resistance of 100 ω and deflects full-scale at 2.00 ma. what size resistor should be added to the galvanometer to convert it to a milliammeter capable of reading up to 4.00 ma, and how should this resistor be connected to the galvanometer?
