The atomic mass, or mass number, of an element tells you the total number of protons and neutrons in one atom of the element. If you know the atomic number of the element and the mass number, you can figure out how many protons and neutrons are in the nucleus of one atom.

Calculate the electric force an electron exerts upon a proton inside a He atom if they are d=2.7⋅10^-10m apart.

maksim [4K]

Explanation:

Charge of electron in He, $q_e=1.6\times 10^{-19}\ kg$

Charge of proton in He, $q_p=1.6\times 10^{-19}\ kg$

Distance between them, $d=2.7\times 10^{-10}\ m$

We need to find the electric force between them. It is given by :

$F=k\dfrac{q_eq_p}{d^2}$

$F=-9\times 10^9\times \dfrac{(1.6\times 10^{-19}\ C)^2}{(2.7\times 10^{-10}\ m)^2}$

$F=-3.16\times 10^{-9}\ N$

Since, there are two protons so, the force become double i.e.

$F=2\times 3.16\times 10^{-9}\ N$

$F=6.32\times 10^{-9}\ N$

So, the correct option is (c). Hence, this is the required solution.
