What is the strength of the electric field 5.2 cmcm from a small plastic bead that has been charged to -9.0 nCnC

The strength of the electric field is 29922.34 N/C

Explanation:

Given;

distance of the electric field, d = 5.2 cm = 0.052 m

charge of the small plastic bead, q = -9 nC = - 9 x 10⁻⁹ C

The strength of the electric field is calculated as;

where;

E is the electric field strength

k is coulomb's constant = 8.99 x 10⁹ Nm²/C²

Therefore, the strength of the electric field is 29922.34 N/C

they should be similar or the same
