... 14) You drop a bowling ball from the top of a tall building. One second later, you drop a pingpong ball from the same point. Neglecting air resistance, what can we say about the motion of the two balls? A) The bowling ball will hit the ground more than one second before the ping-pong ball. B) The bo ...

... Potential difference: ΔVab ≡ V ( r = b ) − V ( r = a ) = ∫ ∇V ( r )id = − ∫ E ( r )id This is true for any end-points a & b (and any contour from a → b). Thus the two integrands must be equal: E ( r ) = −∇V ( r ) Differential Version Now (for electrostatics): ∇ × E ( r ) = 0, Thus: ∇ × E ( r ) = ∇ × ...
