Answer:
Similarities between electrostatic and gravitational interactions: 1. Both forces act according to similar laws: \[F=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{{{q}_{1}}{{q}_{2}}}{{{r}^{2}}}\]and \[F=G\frac{{{m}_{1}}{{m}_{2}}}{{{r}^{2}}}\] 2. Both are conservative forces. 3. Both are central forces. Dissimilarities between electrostatic and gravitational interactions: 1. Electrostatic interactions may be attractive or repulsive while gravitational interactions are always attractive. 2. Electrostatic interactions depend on the nature of the medium while gravitational interactions do not depend on the nature of the medium. 3. Electrostatic interactions are much stronger than gravitational interactions.
