2. Two charges of 10 C and -4 UC are 2.0m apart. What is the potential at a point midway between these charges? 3. Two-point charges qi = +4.00 nC and q.= -3.00 nC are 0.100m apart. Point A is midway between them: point B is 0.80m from q, and 0.060m from q2. Find thepotential at (a) point A (b) point B. Electric Potential: Work 1. How much work is required to move the +12mC charge from the 15cm position to the 25cm position? 2. How much work is required to carry an electron from the positive terminal of a 12-V battery to the negative terminal? 3. How much work is needed to move a -8.6 UC charge from ground to a point whose potential is +75V
