Two charged spherical conductors are connected by a long conducting wire,and a charge of 19.9uC is placed on the combination.If the first sphere has a ridius of 3.73cm and the second has a radius of 6.24cm,what's the electric field of each sphere?那最后要求的是 电场强度？怎么算？

答
设其中的一个带电量为q,另一个就是19.9－q.两个球的电势相等,电势＝电量÷(4×pai×真空介电常数×半径),剩下的你自己求吧,我没装备.
