Two positive charges of 5.43 µC each are
508 cm apart.
Find the electric ﬁeld midway between
them.

What is the magnitude of the electric ﬁeld if
one charge is positive and the other negative,
both of magnitude 5.43 µC?

• physics -

if they are the same charge, halfway there is zero E.

if they are different,

E=2*kq/(508/2)^2

• physics -

Why did you do 2 times kq
