SOLVED - $100

Let $\hat{R}(G)$ denote the size Ramsey number, the minimal number of edges $m$ such that there is a graph $H$ with $m$ edges such that in any $2$-colouring of the edges of $H$ there is a monochromatic copy of $G$.

Is it true that, if $P_n$ is the path of length $n$, then \[\hat{R}(P_n)/n\to \infty\] and \[\hat{R}(P_n)/n^2 \to 0?\] Is it true that, if $C_n$ is the cycle with $n$ edges, then \[\hat{R}(C_n) =o(n^2)?\]
