Which of the following universal forces is the weakest? 
A) electric
B) gravitational
C) magnetic
D) strong nuclear

I also need some explanation for this one 

Sagot :

Well, electric and magnetic are actually the same in nature (as basic force in the Universe). The four, in decreasing order of strength, are:
Strong nuclear, Weak nuclear, Electric/Magnetic (in roughly the same range) and Gravitational (much weaker than Electric/Magnetic -- a magnet less than 1 kg beats Earth which is quite a lot of gigatons, roughly)

Answer:

Option (B)

Explanation:

The gravitational force is usually defined as the force of attraction that occurs due to the presence of the object's mass. The mass of the object and the force of gravity is directly proportional to each other. At the atomic as well as at the subatomic levels, this gravitational force of gravity is comparatively so weak because the masses of these atoms, subatomic particles are extremely very small. This force has a strength of about 10^-40 and this far smaller in comparison to the strength of electromagnetism.

On the other hand, the other universal forces such as the electric force, magnetic and strong nuclear force are very much stronger than the gravitational force. The nuclear force is strongest of all, where it is 100  times stronger than the electromagnetic force and approximately 10^36 times stronger than the gravitational force.

Thus, the correct answer is option (B).
