a). $(1)$ the tension increases. b). $3465N$ in each cable.

a). The tension will increase (1). Because as $\theta$ decreases, $sin\theta$ also decreases. However, the vertical component of both the cables together is $2Tsin\theta$ which is equal to $mg$ is fixed. So, if $sin\theta$ decreases, T should increase. b). $2Tsin45^{\circ}=mg$ $T=\frac{500\times9.8}{2\times\frac{1}{\sqrt 2}}=3465N$
