The total charge on 4 particles is −36 units. all the particles have the same charge. what is the charge on each particle? −9 units −8 units 8 units 9 units

Charge on each particle is -9 units.

Step-by-step explanation:

We know that,

number of particles = 4; and

the total charge of particles = -36

Since, all the four particles have an equal charge, we can simply divide the total charge by 4 to find the charge on each particles.

Charge on each particle = = units

Also, the charge on each particle must be negative since the total charge given is '-36'.

the expected value of the random variable : 0, 1 and 2
