`{:(,"List-I",,"List-II"),((A),"Strong nuclear force",(i),10^(-2)),((B),"Weak nuclear force",(ii),1),((C),"Elextromagnetic force",(iii),10^(-39)),((D),"Gravitational force",(iv),10^(-13)):}`
The correct match is

Options

A. `{:("A","B","C","D"),("(ii)","(iv)","(i)","(iii)"):}`
B. `{:("A","B","C","D"),("(iii)","(ii)","(iv)","(i)"):}`
C. `{:("A","B","C","D"),("(ii)","(iii)","(iv)","(i)"):}`
D. `{:("A","B","C","D"),("(iv)","(ii)","(i)","(iii)"):}`

Answer

A

Explanation

(a) The four fundamental forces of nature are as follows,
(i) Strong nuclear force which is between nuclear particles like, quarks. Its strength is very high and of the order of 1.
But it's range is very short.
(ii) Weak nuclear force which is also between nuclear particles, however its strength is low and of the order of `10^(-13)`. This force is usually found in radioactive nuclei. It is also a short range force.
(iii) Electromagnetic force which is the force between the electrically charged particles. Its strength is of the order of `10^(-2)`. But its range is very high, upto infinity.
(iv) Graviational force which is the force of attraction between bodies due to gravity. Its strength is very low and of the order of `10^(-39)`. But it's range is very high upto infinity.
So, the correct sequence of match is `A rarr (ii), B rarr (iv), C rarr (i)` and `D rarr (iii)`.
