Problem

A lamp of weight

100\,\text{N}

is suspended by two light strings attached to the ceiling. String A makes an angle of

60^\circ

with the ceiling on the left side, and string B makes

30^\circ

on the right side. The lamp is in equilibrium. The tension in string A is a)

75\,\text{N}

100\,\text{N}

86\,\text{N}

50\,\text{N}
