QUESTION #20 Electrostatic Potential Energy
Two charges q_1 and q_2 are separated by a distance of 30 cm. A third charge q_3 initially at 'C' as shown in the figure, is moved along the circular path of radius 40 cm from C to D. If the difference in potential energy due to movement of q_3 from C to D is given by fracq_3K4pi in_0 , the value of K is: {{IMG1}}
