Question

if body has static friction then the acceleration of the body is zero or not?

Answer 1

As a force that opposes motion, friction always reduces acceleration. Friction occurs between the interaction of an object against a surface. Its magnitude depends on the characteristics of both the surface and the object, and whether the object is moving or not.

Answer 2

Static friction is applied on an object which is on the verge of motion or simply, it is about to move.

This means that when static friction is applied, the object is not in motion. So, the accleration is also zero.
