You're initially flying your scooty puff jr. spaceship in the galactic western direction. sometime later you're flying at the same speed in the galactic southern direction. what is the direction of the average acceleration on the ship during this time

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
