An electric field of 3 × 1016 is needed to create a spark in the air. if the charged particles in the field are separated by a distance of 1 mm, how many coulombs of charge are needed for a spark?

There are 3.34 C of charge are needed to spark.

Explanation:

Given that,

Electric field,

If the charged particles in the field are separated by a distance of 1 mm, d = 1 mm

The electric field is given by the formula as follows :

q is charge

So, there are 3.34 C of charge are needed to spark.

the answer would be c. motion and direction

i hope this : )
