Good. You can do some very interesting experiments with that equipment.
B-things that can attract iron.
Answer:
1.93 x 10∧3 N
Explanation:
The picture attached shows the calculation
Answer:
magnetic fields is stronger at the pulls because opposites attract which is why the pull is stronger.
this was written by me.
Explanation:
Answer:
The value of new coulomb force is 1.43 N.
Explanation:
Given;
Coulomb's force in vacuum (air),
= 10 N
dielectric constant, K = 7
The Coulomb's force between two charges separated by a distance r in a vacuum is given as;

The Coulomb's force between two charges separated by a distance r in a medium with dielectric constant is given as

Take the ratio of the two forces;

Therefore, the value of new coulomb force is 1.43 N.
