Question

What is electric field? Determine the electric field due to a system of charges.l​

Answer 1

Answer:

Electric field due to a system of charges | Definition, Examples ...

Solution In the given equilateral triangle ABC of sides of length l, if we draw a perpendicular AD to the side BC, AD=ACcos30=(3 /2)l and the distance AO of the centroid O from A is (2/3)AD=(1/3 )l. By symmetry AO = BO = CO. Therefore, the total force on Q=4πϵ0l23Qq(r^−r^)=0 where r^ is the unit vector along OA.

Answer 2

a region around a charged particles or object within which a force would be exerted on other charged particles or object is called electric field
