A shop sign of mass

30\,\text{kg}

is suspended by two identical light cables that make equal angles of

30^{\circ}

with the vertical. Take

g = 10\,\text{m\,s}^{-2}

. What is the tension in each cable? (a)

1.50\times10^{2}\,\text{N}

(b)

3.46\times10^{2}\,\text{N}

(c)

1.73\times10^{2}\,\text{N}

(d)

3.00\times10^{2}\,\text{N}
