Question

When 1013 electrons are removed from a
neutral metal sphere, the charge on the
sphere becomes:
a) 16 uc
b) 1.6 IC
c) 0.16mc
d) 0.6 uc​

Answer 1

Answer:

+1.6 uC

Explanation:

removed electrons are removes and sphere already neutral so remaining positive charge will be appear on sphere.

Q = n e = 1.6x10^-19x10^13 = 1.6x10^-6=1.6 uC

Answer 2

Answer:

Option b

Explanation:

Among the four options given in question statement, the correct option is option b.

We are given that there is a nuetral sphere, it means the net charge on it is zero.

Now we remove 10^13 electrons. Let us first calculate the charge on these electrons;

Equation that we would be using;

Q = n e

  = 1.6x10^-19 x 10^13

  = 1.6x10^-6

  =1.6 uC

So this 1.6 uC negative charge would be taken out from the neutral sphere, here the sphere would psoitively charged by 1.6 uC
