Total energy of a system is always conserved, no matter what internal and external forces on the body are present.
False Although internal forces are balanced, they cause no work to be done on a body. It is the external forces that have the ability to do work. Hence, external forces...

You can shield a charge from electrical forces by putting it inside a hollow conductor.
No Gravitational influence of matter on nearby objects cannot be screened by any means. This is because gravitational force unlike electrical forces is independent of the nature of the material medium....
