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.
