answer ex 2 and 3 1. Two point charges q, = +26µC and q2 = -17.5µC are 64 cm apart.a. What is the potential energy of the system of two charges?b. What is the electric potential at a point between them 24 cm from q,?2. Three point charges q, = +2.7µC, q2 = -3.4µC and q3 = -1.6µC initially are infinitely far apart. They are thenbrought together and placed at the corners of an equilateral triangle. Each side has a length of 40 cm.Determine the total electric potential energy of these group of charges.3. Two point charges q, = 2.2nC and q2= -1.5nC are 13 cm apart. Point A is midway between the charges andpoint B is 12 cm from q, and 5 cm from q2. Calculate:a. the electric potential at point A and at point Bb. the work done by the electric field on a charge of q3 = +3.6nC that moves from A to B4. A certain amount of excess charge is transferred a conducting sphere with a diameter of 30 cm such thatthe electric potential at the center of the sphere is equal to 2.5 kV.a. How much charge was transferred to the conducting sphere?b. Determine the electric potential at a point outside of the sphere with a distance of 5 cm from its surface.c. Determine the charge density of the sphere. (Hint: surface or volume?)5.
