The dipole moment ((p)) is calculated using the formula: (p = q times d), where (q) is the magnitude of the charge and (d) is the separation distance between the charges.
Given:
– Charge, (q = 2C) (Coulombs)
– Separation distance, (d = 2 cm = 0.02 m) (since (1 cm = 0.01 m))
Therefore,
[p = q times d = 2C times 0.02m = 0.04 Ccdot m]
So, the dipole moment for the given configuration is (0.04 Ccdot m).
Answer: b
Explanation: The dipole moment of charge 2C and distance 2cm will be,
M = Q x d. Thus, M = 2 x 0.02 = 0.04 C-m.
