A positive charge of 94. 0 NC is 22. 0 cm from a negative charge of 53. 0 NC. The force on one of the charges due to the other is approximately 92.6× 10⁹ N
Force between the two charges depends upon the charges, distance between the charges and the medium between the two charges. It is given by:
F = kq₁q₂ / r²
where q₁ is the charge of the first charge
q₂ is the charge of the second charge
r is the distance between the charges
k is the permitivitty of medium
F is the force between the two charges
Given , q₁ = 94NC
q₂ = 53NC
r = 22cm = 0.22m
On subsituting,
F = 9 × 10⁹ × 94 × 53 / (0.22)²
⇒ F = 92.6 × 10⁹ N
Since, the force between the two charges is equal on both the charges hence, force on one of the charges due to the other is approximately 92.6× 10⁹ N.

Answer:
If you break a bar magnet in half, each half <u>becomes a magnet.</u>
Explanation:
A substance which attracts or repels another similar substance is known as magnet. When domains align in single direction in a substance, it acts as a magnet. A magnet has two poles- North pole and South pole. Like poles repel each other and unlike poles attract each other. Mono-poles do not exist. So, when a magnet is broken into two halves, each half forms another magnet with two poles.
If one bulb goes out then all the others won't light up because electricity will be cut off. It's a disadvantage because in a parallel circuit if one bulb burns out all the others will still be on because they won't be affected. I hope I've helped you ☺
The halo extends farther from the nucleus
Answer:
0.120 m
Explanation:
F=kx where F is force and k is constant, x is extension from its original length
Making x the subject then substituting 12 N for F and 10.0 N/m for k then
