The recommendations state that "members of the general public should not be exposed on a continuous basis to electric field strengths exceeding 5 kV/m," or to magnetic fields exceeding 0.1 mT (1 gauss or 1,000 mG).

electric field must not exceed 5000 V / m  ( 5 kV/m)

Explanation:

All electrical equipment produces electric and magnetic fields that must be within the range recommended by WHO, the upper limit for the sum of all fields is

  The electric field must not exceed 5000 V / m

to get an idea of the intensity produced by one of the devices that has the largest electric field in the radio with 180 V / m

Answer

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
