Answer 1

Answer:

hiiiiii

your answer is here !

Explanation:

To calculate the Force between two protons we will apply the simple formulae :

F = K× q1× q2 / r^2

Here => q1 = q2 = 1.6 × 10^-19 C .

distance ( r ) = 20cm = 0.2 m .

K = 9 × 10^9

substituting the values in formulae we get ,

=> F = [ 9 ×10^9 × ( 1.6 ×10^-19 )^2 ] ÷ 0.2^2

➡=>> F = 5.76 × 10^-27 N is the force between two protons !

good morning have a nice day !
