mass can not be -ve. But mass can be negative in one condition,which is only hypothetical & is not applied to any of the theories......this condition is....if the speed orvelocityof a body becomes more than the speed or velocity of light(3*108 m/sec).

In physics, mass is always a positive quantity. Negative mass would have unusual and counterintuitive consequences, such as defying the laws of gravity. As of now, there is no evidence to support the existence of negative mass.
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
A negative change in mass means that the object has lost mass. It could be due to factors such as evaporation, chemical reactions, or loss of particles.
When an object receives a negative charge, there is no change in its mass. Mass is a fundamental property of matter that is not affected by the addition or removal of charge. The negative charge simply alters the distribution of electrons on the object's surface.
The mass of an object does not change when it receives a negative charge. Mass is a measure of the amount of matter in an object, and adding or removing charge does not alter the amount of matter present.
When a negative charge is added to a soap bubble, its mass remains the same. The negative charge affects the bubble's electrical properties but does not change its mass.
