Why is only the speed of light constant in all frames of reference?
The only thing that affects the speed of light is the refractive index of the medium through which it moves, and for space, this number is 1.000000 and gives you the maximum possible speed of light.

If force is acting on a moving body perpendicular to the direction of motion, then what will be its effect on the speed and direction of the body?
The magnitude of velocity shall decrease and direction shall be same till it comes to rest, afterwards it shall move in direction of force with acceleration due to the applied force.
