Question

The amount of charge in a positively charged object is 4.8 × 10-¹⁷C, how many electrons are missing in this object, if the charge of electron is 1.6×10-¹⁹C?​

Answer 1

Answer:

Amount of charge in positively charged object = 4.8×10-¹⁷

Charge in 1 electron = 1.6×10-¹⁹

No. of missing electrons = 1.6×10-¹⁹—4.8×10-¹⁷ = 1.6×10-¹⁷ ( 1×10-²—0.3) = 1.6×10-¹⁷(-0.29) = -0.464×10-¹⁷
