Um corpo tem uma carga igual a -32. 10-6 C. Quantos elétrons há em excesso nele?

a)20x10^13

b)-20x10^13

c)2,0x10^13

d)-2,0x10^13

e)NDA

a) 2*10^14 electrons

Explanation:

To find the amount of electrons you take into account that:

by replacing this values in the factor C of the charge given by the exercise you obtain:

= 2*10*10^13 =20*10^13 electrons (you take the absolute value)

hence, the total number of electrons in a charge of 32*10^-6 C is 2*10^13 electrons

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

the components of a vector are the parts of the vectors that are to each other.

b perpendicular
