According to Coulomb’s law, what will happen to the electric force between two identical negative charges as they move closer together?
A. Fe will become negative and decrease in magnitude.
O B. Fe will stay negative and increase in magnitude.
C. Fe will stay positive and increase in magnitude,
D. Fe will become positive and decrease in magnitude.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
