and
which are separated by the distance
is given by

<em>where,</em> k is the Coulomb's constant.
For the case, when,
Then, using Coulomb's law,

For the case, when,
Then, using Coulomb's law, the new electric force between the charges is given by,

Answer:
648.40N
Explanation:
Centripetal acceleration is the acceleration of an object around a circular path. Centripetal for e acting on the combined mass is expressed as:
F = ma
F = mv²/r
m is the mass of the object = 143kg
v is the linear velocity = 13.8m/s
r is the radius = 42.0m
Substitute the given parameters into the formula;
F = 143*13.8²/42
F = 27,232.92/42
F = 648.40N
Hence the magnitude of the centripetal force acting on the combined mass is 648.40N
Health and safety are two reasons
Explanation:
Amphipathic molecules are the molecules that consists of both polar and non-polar parts.
For example, fats and oils are amphipathic molecules.
Amphipathic molecules have two different parts. One is water loving which is also known as hydrophilic side and other is water fearing which is also known as hydrophobic side.
Molecules that are amphipathic must contain both hydrophilic and hydrophobic regions or parts.
