Minimum charge on any object cannot be less than ______?

کسی بھی شے پر کم سے کم چارج ______ سے کم نہیں ہوسکتا؟

1.8 × 10⁻¹⁶ e

1.3 × 10⁻¹⁴ e

1 × 10⁻¹⁹ e

None of these

The minimum possible charge on any object is the charge of a single electron or proton, which is 1.6 × 10⁻¹⁹ C.

But in terms of elementary charge (e), it is written as 1 × 10⁻¹⁹ e.

No object can have a charge smaller than this because charge is quantized in multiples of e.
