Q. Consider the following statements:
1.Antimatter refers to a type of matter composed of antiparticles.
2.Antiparticles have same mass but opposite charges.
3.Antiparticles are naturally produced in the universe.
Which of the statements given above are correct?
Answer: D
Notes:
Explanations –
Statements 1, 2 and 3 are correct. Antimatter is made up of antiparticles, which are counterparts of ordinary particles with opposite charges but the same mass. For example, the positron (antielectron) has the same mass as an electron but a positive charge instead of a negative charge. Antiparticles are created naturally in processes such as cosmic ray collisions, radioactive decay, and supernova explosions.
