Physics Question-Due in 20 Minutes-I really need help!!!?
Two equal charges, q, are separated by a distance, d. The charges are moved to a distance d/2 apart. What is the work required to do this?
a. + kq / d
b. −kq / d
c. + kq^2 / d
d. −kq^2 / d
e. + kqd
I appreciate any help I can get. This is due in 20 minutes. Thank you in advance for your time!
Update:
Is it choice C because W=Change in Potential Energy? So kq^2/(d/2)-kq^2/d=kq^2/d?
