2. +/10 points SerCP10 16,P.01 5.MIFB Two point charges Q1 = +6.00 nC and Q2 =-2.50 nC are separated by 25.0 cm. (a) What is the electric potential at a point midway between the charges? (b) What is the potential energy of the pair of charges? What is the significance of the algebraic sign of your answer? Positive work must be done to separate the charges. Negative work must be done to separate the charges. Need Help? Read ItMaster It

Explanation / Answer

a)

here by using the formula of potential

V = k * q / r

Vtotal = V1 + V2

Vtotal = k * 6 * 10^-9 / 0.125 - k * 2.5 * 10^-9 / 0.125

Vtotal = 252 V

b)

potential energy of the charges = k * q1 * q2 / r

U = (9 * 10^9 * 6 * 10^-9 * -2.5 * 10^-9) / 0.125

U = -1.08 * 10^-6 J

c)

negative work must be done to seperate the charges
