Electrostatics question

2022 · 28 Jul · Shift 1 · Q67

JEE MainPhysicsElectrostaticsNumerical+4 / −1
Two electric dipoles of dipole moments 1.2×10−30 Cm1.2 \times 10^{-30} \,\mathrm{Cm}1.2×10−30Cm and 2.4×10−30 Cm2.4 \times 10^{-30} \,\mathrm{Cm}2.4×10−30Cm are placed in two different uniform electric fields of strengths 5×104 NC−15 \times 10^{4} \,\mathrm{NC}^{-1}5×104NC−1 and 15×104 NC−115 \times 10^{4} \,\mathrm{NC}^{-1}15×104NC−1 respectively. The ratio of maximum torque experienced by the electric dipoles will be 1x\frac{1}{x}x1​. The value of xxx is ‾\underline{\hspace{2cm}}​.
