Question

calculate and compare the electostatic and gravitational force between two protons which are 10^-15 m apart value of g = 6.674×10^-11 m^3 kg^-1 and mass of the proton is 1.67×10^-27kg​

Answer 1

Answer:

electrostatic force using the formula: F = K[q1 x q2]/D^2 where K is coulombs constant, which is equal to 9 x 10^9 Nm^2/C^2 and

Electric charge +1 e = 1.602176634×10−19 C

F = K[q1 x q2]/D^2

=9*10^9 *1.602176634×10−19*1.602176634×10−19/10^-30

= 23.04*10 = 230.4 N

Gravitational force,

F = G*m1*m2/r^2

= 6.674×10^-11*1.67×10^-27*1.67×10^-27/10^-30

= 18.60*10^-35 N
