Question

A point charge gives rise to an electric field of 3 N/C at a distance of 5 m. If the distance remains the same and the charge is increased by a factor of 10, then what will be the new electric field? 30. N/C 0.30 N/C 3.0E+02 N/C 60. N/C 0.030 N/C

Answer 1

Electric field is directly proportional to charge.

If charge get increases by a factor of 10,then electric field will also get increases by a factor of 10.

Since old is 3N/C,

New becomes 3×10=30 N/c
