- Two opposite and equal charges 4 x 10-8 C when placed 2 x 10 cm away, form a dipole. If this dipole is placed in an external electric field 4x108 N/C. the value of maximum torque and the work done in rotating it througn 180° will be (a) 64 × 10 N-m and 64 × 10- J (b) 32 x 10 N-m and 32 × 10J (c) 64 ×10* N-m and 32 x 10-4 J -4 (d) 32 x 10 N-m and 64 × 10* J
