Question

Which of the following is not a condition of validity of coloumbs law,

• A. The charges must be stationary with respect to each other.
• B. The charges must not overlap (e.g. be distinct point charges)
• C. The charges must have a spherically symmetric distribution (e.g. be point charges, or a charged metal sphere.
• D. Charge must have some mass

Answer 1

The correct option is D Charge must have some mass

The conditions for Coulomb's law to be valid is:
i) The charged objects must have spherical geometry.
ii) Charges should not be moving relative to each other.
iii) The charges must be distinct point charges.
