一道大学物理题（由于小弟英语授课）英文题目
Two small,positively charged spheres have a combined charge of 2.5×10-5C.If each sphere is repelled
from the other by an electrostatic force of 1N when the
spheres are 2 m apart,what is the charge on the sphere
with the smaller charge?
我感觉应该是一道很简单的物理题
首先依题意 q1+q2=2.5X10^-5C 然后由那个库仑定律 F=q1*q2/4πE*r^2=1
可以得出一个q1*q2的关系式.但是我怎么算也算不出来.

此题求的是带电量较小的电荷带电量
利用两个电荷之和与之积,求出差的平方,进而求出差的绝对值,假设q1＞q2
那么现在就有q1+q2以及q1-q2的值了,两个值想减再除以2就是q2的值,也就是所要求的带电量较小的电话带电量了
库仑定律 F=q1*q2/4πE*r^2=1 ？？E=？？
F=Kq1*q2/r^2
