Answer:
Atoms are electrically neutral because there are an equal number of protons in the nucleus and In the cloud around the nucleus.
Explanation:
- The atoms that are the building block of matter consist of protons, neutrons, and electrons.
- The protons are positively charged and the electrons are negatively charged particles.
- The neutrons are negatively charged particles.
- The atoms in its stable natural state consist of an equal number of protons and electrons.
- Thus an atom has a neutral charge in its natural state.
Answer:
By exact formula
5076.59N/C
And by approximation formula
5218.93N/C
Explanation:
We are given that
Length of rod,L=2.6 m
Charge,q=98nC=
a=13 cm=0.13 m
1 m=100 cm
By exact formula
The magnitude of the electric field due to the rod at a location 13 cm from the midpoint of the rod=
Where k=
Using the formula
The magnitude of the electric field due to the rod at a location 13 cm from the midpoint of the rod=
In approximation formula
a<<L
Therefore,the magnitude of the electric field due to the rod at a location 13 cm from the midpoint of the rod=
The magnitude of the electric field due to the rod at a location 13 cm from the midpoint of the rod=
The centrifugal force working against the car would be the entire car's weight, so the centripetal force that is supplied to the car must be the car's tires traction, aka the friction of the car's tires and the surface.
