Determine the electrical and gravitational forces that two protons in the nucleus of a helium atom exert on each other when separated by 3.0×10−15m. express your answer to two significant figures and include the appropriate units (g = 6.67 × 10-11 n ∙ m2/kg2, mproton = 1.6726231 × 10-27 kg, qproton, 1.6021 × 10-19 c k = 9 × 109 n ∙ m2/c2)

Fe = 25.67 N

Fg = 2.0734 x 10^-35 N

Explanation:

r = 3 x 10^-15 m

G = 6.67 x 10^-11 Nm^2/kg^2

Mp = 1.6726231 x 10^-27 kg

Qp = 1.6021 x 10^-19 C

K = 9 x 10^9 Nm^2/C^2

The formula for the electrical force between the two protons is given by

Fe = 25.67 N

The formula for the gravitational force between the two protons is given by

Fg = 2.0734 x 10^-35 N

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
