Question : 86 of 160

Marks: +1, -0

Two opposite and equal charges each of magnitude 4×10−8C form a dipole. Their separation is 2×10−2cm. When this dipole is placed in an external electric field 4×108N.C−1, the value of maximum torque and the work done in rotating it through 180° respectively, will be

64×10−4N.m & 64×10−4J
32×10−4N.m & 32×10−4J
64×10−4N.m & 32×10−4J
32×10−4N.m & 64×10−4J
