JEE MainPhysicsElectrostaticsMCQ+4 / −1
Two charges q1q_1q1​ and q2q_2q2​ are separated by a distance of 30 cm . A third charge q3q_3q3​ 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 q3q_3q3​ from C to D is given by q3 K4πϵ0\frac{q_3 \mathrm{~K}}{4 \pi \epsilon_0}4πϵ0​q3​ K​, the value of K is : JEE Main 2025 (Online) 7th April Morning Shift Physics - Electrostatics Question 6 English
