Answer 2

Coulomb's force between 2alpha particles is 90 N

Explanation:

• Coulomb's force is the force exerted by stationary objects bearing electric charge on the other stationary objects bearing the same or different electric charge can be greater ,lesser or equal to the first one. If the charge is of same sign then the force is repulsive if they are of opposite signs, the force is attractive. the strength of force is explained by coulombs law.

the formula to caculate force is

F= k × q1×q2÷ r²

where, F is electric force

          k is coulomb constant=9×10⁹ Nm² /C²

        q1,q2 are charges

        r is distance of seperation  

so in question we take charge as 2e because they are given as alpha particle and putting the respective values we get 90 N coulomb,s force.
