1.	Two equal and opposite charges of 4×10−8 C when placed 2×10−2 cm away, form a dipole. If this dipole is placed in an external electric field of 4×108 newton/coulomb, the value of maximum torque and the work done in rotating it through 180∘ will be
Answer» Two equal and opposite charges of $4 \times 10^{- 8}$ C when placed $2 \times 10^{- 2} c m$ away, form a dipole. If this dipole is placed in an external electric field of $4 \times 10^{8}$ newton/coulomb, the value of maximum torque and the work done in rotating it through $180^{\circ}$ will be
