Two equal positive charges are separated by d.Then one of the charges is replaced by a negative charge of the same magnitude.Take the potential at infinity to be zero.In which situation is the potential higher midway between the charges;is this value of potential zero?
A) the first situation;yes
B) the first situation;no
C) the second situation;yes
D) the second situation;no

In the first situation, with two equal positive charges, the potential at the midpoint is higher because both charges contribute positively to the potential. The potential is not zero because the contributions from both charges add up.
