Physics
1 answer:
Ber [7]3 years ago
7 0

Answer:

Explanation:

the net force on the right left is 25 N and is directed upward

the net force on the left one is zero because 200N force act upward and 200N force act downward so both cancel each other and net force is zero

i hope this will help you

Determine the electrical and gravitational forces that two protons in the nucleus of a helium atom exert on each other when sepa
jonny [76]

Answer:

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

F = K \frac{Q_{p}\times Q_{p}}{r^{2}}

F = \frac{9\times 10^{9}\times 1.6021\times 10^{-19}\times 1.6021\times 10^{-19}}{3\times 10^{-15}\times 3\times 10^{-15}}

Fe = 25.67 N

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

F = G \frac{M_{p}\times M_{p}}{r^{2}}

F = \frac{6.67\times 10^{-11}\times 1.6726231\times 10^{-27}\times 1.6726231\times 10^{-27}}{3\times 10^{-15}\times 3\times 10^{-15}}

Fg = 2.0734 x 10^-35 N
