The value of electric charge on any objects cannot be less than:

(A) 4.8x10-19C

(B)1.6x10-19C

(c)3.2X10-19C

(D)1C

AA

BB

CC

DD

Answer:

B. B

Read Explanation:

  • Electric charge is quantized, meaning it exists in discrete, indivisible units.

  • This principle states that the total electric charge on any object is always an integer multiple of the elementary charge, denoted by 'e'.

  • Mathematically, this is expressed as Q = n * e, where 'Q' is the total charge, 'n' is an integer (..., -2, -1, 0, 1, 2, ...), and 'e' is the elementary charge.

Elementary Charge (e)

  • The elementary charge 'e' is the magnitude of the charge of a single electron or a single proton.

  • Its value is approximately 1.602 x 10-19 Coulombs (C).

  • The charge of an electron is -e, and the charge of a proton is +e.

  • The elementary charge 'e' ≈ 1.6 x 10-19 C.
