)what is the electric potential due to the nucleus of hydrogen at a distance of 7.50× 10-11 m? assume the potential is equal to zero as r→∞. (express your answer to three significant figures.)

Electric potential, V = 19.2 volts

Explanation:

In this case we need to find the electric potential due to the nucleus of hydrogen at a distance of . For this we must know the concept of electric potential. It is the work done in moving a charged particle in electric field from zero to a particular point. Its formula is given by :

q is the charge of nucleus of hydrogen i.e. proton

So, the electric potential due to the nucleus of hydrogen at a given distance is 19.2 volts. Hence, this is the required solution.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
