Answer 1

The following are the TRUE choices,

(d) an electric dipole consists of two separated electric charges that have the same amount of electric charge but opposite polarity.

( e ) a mass weigh 100 N at the surface of earth. If the same mass was placed at the bottom of a hole that is 3000 m deep into the earth, the weight would be less than it is at the surface of earth.

The acceleration due to gravity decreases as we go deep into earth and hence the weight also decreases.
