A function $$n(x)$$ satisfies the differential equation $${{{d^2}n\left( x \right)} \over {d{x^2}}} - {{n\left( x \right)} \over {{L^2}}} = 0$$ where $$L$$ is a constant. The boundary conditions are $$n(0)=k$$ and $$n\left( \propto \right) = 0.$$ The solution to this equation is
A
$$n\left( x \right) = k\,\exp \left( {{{ - x} \over L}} \right)$$
B
$$n\left( x \right) = k\,\exp \left( {{{ - x} \over {\sqrt L }}} \right)$$
C
$$n\left( x \right) = {k^2}\,\exp \left( {{{ - x} \over L}} \right)$$
D
$$n\left( x \right) = {k^2}\,\exp \left( {{{ - x} \over {\sqrt L }}} \right)$$
