Question

solve this que of physics​

Answer 1

the electrostatic force will remain same...

Answer 2

remains same as

Coulombs force depends upon

$f = kq1q2 \div r {}^{2}$

if both charges are increased by 2 times and distance is also increased by two times

new f(n)

$f(n) = 4kq1q2 \div (2r) {}^{2} \\ = 4kq1q2 \div 4r {}^{2}$

f(n)=kq1q2÷r^2

f(n)=f

i.e force remains same
