Physics - Electrostatics Question with Solution | TestHub

the magnitude of electric field ${\mathrm{E}}_{\mathrm{x}}$ at $\mathrm{x}=-2\mathrm{m}$ is $3\mathrm{N}/\mathrm{C}$

the electric field ${\mathrm{E}}_{\mathrm{x}}$ at $\mathrm{x}=1\mathrm{m}$ is $6\mathrm{N}/\mathrm{C}$

the work done in moving a charge particle per unit charge from $\mathrm{x}=-3\mathrm{m}$ to $\mathrm{x}=1\mathrm{m}$ is $6\mathrm{J}/\mathrm{C}$

the work done in moving a charge particle per unit charge from $\mathrm{x}=2$ to $\mathrm{x}=\infty$ is $-6\mathrm{J}/\mathrm{C}$
