A particle of mass 10 kg is held in equilibrium by two light strings and a horizontal force of 20 N. The strings lie on opposite sides of the vertical. String 1 is inclined at 30° 30°\,30° to the horizontal and string 2 is inclined at 60° 60°\,60° to the horizontal. The horizontal force acts towards the side of string 2.
Use g=9.8g=9.8g=9.8 m s−2^{-2}−2.
Find the tension in each string, giving exact values and values to 3 significant figures.
