Question

please simplify this ....​

Answer 1

See, Charge of electrons is (-)ve but when solving questions, esp. like these, we only take the magnitude,i.e, 1.6×10^-19.

I solved it accordingly☝️

Also if you're wondering how I got "20/16" I just multiplied 10 on both numerator and denominator side, i.e, "2×10/1.6×10" to ease the calculation.

You could directly write the value of 2/1.6 if you want.

Hope it helps!
