JEE AdvancedPhysicsElectrostaticsMCQ+3 / −1
An electric dipole is formed by two charges +q+q+q and −q-q−q located in xyx yxy-plane at (0,2)mm(0,2) \mathrm{mm}(0,2)mm and (0,−2)mm(0,-2) \mathrm{mm}(0,−2)mm, respectively, as shown in the figure. The electric potential at point P(100,100)mmP(100,100) \mathrm{mm}P(100,100)mm due to the dipole is V0V_0V0​. The charges +q+q+q and −q-q−q are then moved to the points (−1,2)mm(-1,2) \mathrm{mm}(−1,2)mm and (1,−2)mm(1,-2) \mathrm{mm}(1,−2)mm, respectively. What is the value of electric potential at PPP due to the new dipole? JEE Advanced 2023 Paper 2 Online Physics - Electrostatics Question 9 English
