Question

For a proton moving in the direction of the electric field

the electric force on the proton does positive work because the force is along the direction of motion.

the electric force on the proton does negative work because the force is along the direction of motion.

the electric force on the proton does positive work because the force is opposite to the direction of motion.

the electric force on the proton does negative work because the force is opposite to the direction of motion.

the electric force on the proton does positive work because the force is along the direction of motion.

the electric force on the proton does negative work because the force is along the direction of motion.

the electric force on the proton does positive work because the force is opposite to the direction of motion.

the electric force on the proton does negative work because the force is opposite to the direction of motion.

electric force=charge*electric field

in case of a proton, charge is positive, and force is along the direction of the field

as it is moving along the direction of the field, displacement is along the direction of the field/

hence net work done=dot product of force and displacement

is positive.

hence first option is correct.
