Two electric dipoles of dipole moments 1 . 2 × 10 - 30 cm and 2 . 4 × 10 - 30 cm are placed in two difference uniform electric fields of strengths 5 × 10 4 N C - 1 and 15 × 10 4 N C - 1 respectively. The ratio of maximum torque experienced by the electric dipoles will be 1 x . The value of x is _____ .

Correct answer

0

Step-by-step solution

Maximum torque experienced by an electric dipole is τ m a x = P E sin 90 ° . So, τ max = P E The ratio is τ 1 τ 2 = P 1 E 1 P 2 E 2 = 1 . 2 × 10 - 30 × 5 × 10 4 2 · 4 × 10 - 30 × 15 × 10 4 = 1 6 Hence, the value of x = 6 .
