Electrostatics question

2021 · 18 Mar · Shift 2 · Q68

JEE MainPhysicsElectrostaticsNumerical+4 / −1
An infinite number of point charges, each carrying 1 μ\muμ C charge, are placed along the y-axis at y = 1 m, 2 m, 4 m, 8 m ............... The total force on a 1C point charge, placed at the origin, is x ×\times× 103 N. The value of x, to the nearest integer, is ‾\underline{\hspace{2cm}}​. [Take 14πε0=9×109{1 \over {4\pi {\varepsilon _0}}} = 9 \times {10^9}4πε0​1​=9×109 Nm2/C2]
