If the energy of a hydrogen atom in nth orbit is E_(n) , then energy in the nth orbit of a singly ionised helium atom will be

If n geometric means are inserted between two quantities ; then the product of n geometric means is the nth power of the single geometric mean between two quantities.

If n geometric means are inserted between two quantities; then the product of n geometric means is the nth power of the single geometric mean between two quantities.

In the curve x^(m+n)=a^(m-n)y^(2n), prove that the mth power of the sub-tangent varies as the nth power of the sub-normal.

The energy of hydrogen atom in nth orbit is E_n . Then the energy in nth orbit of single ionised helium atom will be
