When dealing with practical devg+zkj; 8uliuc cqf,p ls3:- :uices, we often take the ground (the Earth) tovz:hp)3t 1gwueq))yi 9( ow er be 0 V. If, instead, we said the ground was how would this affect (a) the potential V, anhu1)(qe)vo rz3ty wgwep:i)9 d (b) the electric field E, at other points?
参考答案: (a) V would decrease by 10 V at every location.
(b) E is related to the change in electric
potential. Decreasing the potential by
10 V everywhere
would not affect the changes in potential from one location to
another, and so would not affect E.
