Question

A ball of mass m and weight mg is held at rest by two strings. One string makes an angle θ with the vertical. The other is horizontal. What is the tension in the horizontal string?.

Answer 1

W = M g weight of ball

T cos θ = W balancing vertical forces

T sin θ = F balancing horizontal forces

tan θ = F / W dividing equations

F = W tan θ when θ equals zero F equals zero
