Ahydrogen atom is at the earth’s surface. the electron and proton in the atom are separated by a dis- tance of 5.29 3 10211 m. what is the ratio of the magnitude of the electrical force exerted by the proton on the electron to the weight of the electron?

Explanation:

As we know that the charge on electron and proton is same as the charge of an electron

so the electrostatic force between the electron and proton is given as

so we will have

Now the weight of an electron is given as

now the ratio of electrical force and weight of the electron is given as

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
