50 pj of energy is stored in a 2.0 cm * 2.0 cm * 2.0 cm region of uniform electric field. what is the electric field strength?

The electric field strength is 1188.46 N/C.

Electric field strength is the force per unit charge in a given region of space.

Relationship between electric field strength and energy stored is given as;

where;

The electric field strength is calculated as follows;

Energy stored in electric field region is given by

here we know that

U = 50 pJ

Now we can use above formula to find the electric field strength

by solving this equation we will have

28. evolution

29. environment, survive, offspring  

explanation:

the answer is 12 as i may remember
