Question

please i need the answer in decimal not like this (1.02*10^3) i dont need it like this i need it only numbers like 20.4 like this. thanks

What is the magnitude of a point charge in coulombs whose electric field 61 cm away has the magnitude 2.6 N/C? Units C Number A certain atom has 71 protons. Assume that the nucleus is a sphere with radius 6.79 fm and with the charge of the protons uniformly spread through the sphere. At the nucleus surface what are (a) the magnitude and (b) direction (radially inward or outward) of the electric field produced by the protons? Units N/C or V/m (a) Number outward (b)

Explanation / Answer

1)

we know that

kq/r^2 = E

E = 2.6 N/c

so substituting given values we get

q = 0.00000000010749 C
