Sample Questions in this Chapter

QUESTION #0 Electrostatic Potential Energy
Two charges q₁ and q₂ are separated by a distance of 30 cm. A third charge q₃ 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 q₃ from C to D is given by (q₃ K)/(4π ε₀) , the value of K is: {{IMG1}}
