Explanation:
difference between the value of one main scale division and one vernier scale division
A neutron is a particle that it doesn´t carries charge, a neutron is a neutral particle.
An electron is a particle that carries a negative charge, and a proton is a particle that carries a positive charge.
b.False.
Good luck.
Answer:
7.401 * 10^(-15) N
Explanation:
30 electrons will have a charge:
30 * -1.6022 * 10^(-19) C
= - 4.806 * 10^(-18) C
The relationship between electric field and electric force is:
E = F/q
This means that force, F, is
|F| = |E|*|q|
|F| = |1540| * |-4.806 * 10^(-18)|
|F| = |-7401.24 * 10^(-18)|
|F| = 7.401 * 10^(-15) N
