Question with large number?electron charge?
The electric charge of an electron is -1.6 x 10^-19 C. What is the force exerted between two electrons separated by one meter? Is it attractive or repulsive?
F= K Q1Q2 / D^2
Im horrible with large numbers and especially at negative exponents...so this is a guess
K = 9x 10^9 N x m^2/c^2
Q1 = -1.6 x 10^-19 C
Q2 = -1.6 x 10^-19 C
D= 1 m
F= 9 x 10 ^9 N x m^2 X ( -1.6x 10 ^-19 C x -1.6x 10 ^-19 C / 1^2 m)
F= 9 x 10 ^9 N x m X (3.2 x 10^19 C^2 )
F= 28.8 x 10^28 NxmxC^2...is the answer i got...
I know i am completely off but how can i do this ...this is basically math but I am just not with well large numbers...
