The shortest line drawn on a plane joining two points , in Coulomb's law or otherwise, is defined to be a straight line. On a curved surface the shortest line joining two points is called a geodesic which is analogous to a straight line on a plane.
The shortest line between two points in a strong gravitational field would be, I suppose, a geodesic.

It can be a geodesic if the local spacetime is strongly curved. But, as far as the charges and any observer (in the curved reference frame) are concerned, the line will always 'look' straight to them.

only only only only straight. if u wana use a curved one u hve to use calculus, assuming that a part of a curve to be a st. line n den integerating it over the curve,

NO. It has to be straight because that is the shortest distance between those points.

Hey if it is a line, why would it be curved??
I mean, doesn't "line" entail that it is straight?

It can be a curve one, because it is written on the earth.

the distance is the straight line distance

a straight line coz r means displacement

Has to be straight, if not then its Gauss
