Expert Answer:

Gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of distance betwen them.Hence gravity seems so powerful only when we deal with HUGE objects. It's relatively weak for individual particles of matter.On the scale of individual particles, the gravitational force is extremely small, only in the order of 10-38 times that of the strong force.

On the other hand electric force is directly proportional to the charges and inversely proportional to the square of the distance between the charges hence its the charge that comes into play.
All the other three forces comes in the context of sub-atomic particles where in the gravitational force seems weaker than other three basic forces.
