    (a) The total charge of the universe is constant.
    (b) The total positive charge of the universe is constant.
    (c) The total negative charge of the universe is constant.
    (d) The total number of charged particles in the universe is constant.
    digAnsr:   a
    Ans : (a) The total charge of the universe is constant.
    According to the principal of conservation of charge, the net amount of positive charge minus the net amount of negative charge in the universe is always constant. Thus, the total charge of the universe is constant. The total positive charge of the universe may increase or decrease, depending on the total increase or decrease in negative charge. This is the principle of conservation of charge that is universal in nature.
