Given in the question :-

side (r) = 10 cm = 0.1 m

Now Refer to the attachment

Here four point charges +q , 2q , +q , -q are given along with diagonal side 0.1 m .

Now electric field at the intersection point of the diagonals of the square,

Hence the net electric field :-

E = k . ( + q + 2q + q - q ) / r²

E = k .3q / r²

Now put the values .

E = 9 × 10⁹ (3q) / (0.1 /√2)²

E = 9 × 10⁹ × q / 10⁻²

E = 9 × 10¹¹ × 3q

E = 3q (9 * 10^1^1 )

Hence the value of the electric field is E = 3q (9 * 10^1^1 )

Hope it Helps . :-)
