The magnitude of the tension in the string is 9.31 N.

<h3>Tension in the string</h3>

The magnitude of the tension in the string in the horizontal circle formed by the turn table is calculated as follows;

T = Fcos(θ)

where;

F is centripetal force
θ is inclination of the string

$T = \frac{mv^2}{r} \times cos(\theta)\\\\T = \frac{3 \times 4.5^2}{5} \times cos(40)\\\\T = 9.31 \ N$

Thus, the magnitude of the tension in the string is 9.31 N.
