Which among the following cannot be the charge of a charged body?
A. 4.8*10-14 Coulomb
B. 6.4*10-15 Coulomb
C. 5*10-14 Coulomb
D. 3.2*10-10 Coulomb
Answer:C
Which among the following cannot be the charge of a charged body?
A. 4.8*10-14 Coulomb B. 6.4*10-15 Coulomb C. 5*10-14 Coulomb D. 3.2*10-10 Coulomb
Explanation: Charge of a body must be an integral multiple of charge of an electron. 5*10-14 is not an integral multiple of (1.602*10-19 Coulomb) which is equal to the charge of an electron. But we can see that 4.8, 6.4, 3.2 are integral multiples of 1.6.
