Question

1. If the four forces in nature are Fg = Gravitational force, Fem = Electromagnetic force, Fw weak forces, FN = Nuclear force, then the ratio of four forces in increasing order of their magnitudes are? (a) Fo: Fw: Fem : FN= 1: 1013: 1036 : 1038 (b) Fo: Fw: Fem : FN= 1: 1013 : 1023 : 1033 (c) FG : Fw: Fem : FN = 1: 1025 : 1036 . 1028 (d) Fo: Fw: Fem : Fn = 1: 1020: 1036 : 1045 ​

Answer 1

Answer:

Among gravitational, electromagnet and nuclear forces

Nuclear force is strongest and gravitational is the wearest

force.

So F

g

<F

e

<F

n

Answer 2

Given : If the four forces in nature are

 $\[{F_G}\]$ = Gravitational force,

$\[{F_em}\]$ = Electromagnetic force,

 $\[{F_W}\]$ = weak forces

 $\[{F_N}\]$ = Nuclear force

To Find : Ratio of four forces in increasing order of their

Solution :

Relative strength of four fundamental forces are :

Strong nuclear force = 1

Electromagnetic Force =$\[{10^{ - 2}}\]$

weak force = $\[{10^{ - 13}}\]$

Gravitational force = $\[{10^{ - 36}}\]$

Thus,

Relative strength of the Forces in increasing order are  $\[{F_G}\]$ <$\[{F_W}\]$ < $\[{F_em}\]$ <  $\[{F_N}\]$

Hence ratio of force in increasing order are (c) $\[{F_G}\]$ :$\[{F_W}\]$ : $\[{F_em}\]$ : $\[{F_N}\]$ = 1: 1025 : 1036 . 1028
