- DNone
✓
Answer
Correct option: C.
$7/3\, A$
c
Let the current in the loop is $\mathrm{I}$.
Let the current in the loop is $\mathrm{I}$.
then $I = \frac{{{E_{net}}}}{{{R_{net}}}} = \frac{{60 - 25}}{{15}} = \frac{{35}}{{15}} = \frac{7}{3}\,{\mkern 1mu} A$

A donor atom in a semiconductor has a loosely bound electron. The orbit of this electron is considerly affected by the semiconductor material but behaves in many ways like an electron orbiting a hydrogen nucleus. Given that the electron has an effective mass of $0.07 \,m_e$, where $m_e$ is mass of the free electron and the space in which it moves has a permittivity $13 \,\varepsilon_0$, then the radius of the electron's lowermost energy orbit will be close to ................. $\mathring A$ (take, the Bohr radius of the hydrogen atom is $0.53 \mathring A$ )
