An object with greater charge will exert a greater force on an object than an object with smaller charge would. However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law.
Answer:
1917723.40119 m/s
Explanation:
m = Mass of deuteron = 
k = Boltzmann constant = 
T = Temperature = 
RMS velocity is given by

The RMS velocity of the deutrons is 1917723.40119 m/s
Explanation:
It is given that,
An electric dipole consists of charges +2e and -2e separated by 0.82 nm
Charge, 
Distance between charges, 
Electric field strength, 
(a) The magnitude of the torque on the dipole is given by :

When dipole moment is parallel to the electric field, 


(b) When the dipole is perpendicular to the electric field, 

(Since, p = q × d)


(c) When the dipole moment is anti parallel to the electric field, 

Since, 

Hence, this is the required solution.
