... For suspension, the upward & downward forces are in equilibrium; hence mg = qE => q = mg/E . Substituting the given quantities yields answer (1). E is downward but the electrostatic force must be upward to counteract the gravitational force, so q must be negative. 7. A conducting sphere of radius 0. ...

... Newton's Second Law tells us that rate of increase (or decrease) in the speed of something which is moving is proportional to the force acting on it. Imagine that you are riding a bicycle along a perfectly smooth and level road and you decide to stop pedaling. If there is a strong wind pushing agai ...
