प्रश्न
Two particles A and B, of opposite charges 2.0 × 10−6 C and −2.0 × 10−6 C, are placed at a separation of 1.0 cm. Two particles A and B, of opposite charges 2.0 × 10−6 C and −2.0 × 10−6 C, are placed at a separation of 1.0 cm.
उत्तर
Given:
Magnitude of charge, q = 2.0 × 10−6 C
Separation between the charges, l = 1.0 cm
Dipole moment, P = q × l
\[P = 2 \times {10}^{- 6} \times {10}^{- 2} \]
\[ = 2 \times {10}^{- 8} C - \] m
