The angle made by the string is determined as 57.8⁰.
How to calculate the angle made by the string?
The angle made by the string is calculated by applying the following formula as shown below;
T sinθ = mg
where;
- T is the tension of the string
- θ is the inclination of the string
- m is the mass of the ball
- g is acceleration due to gravity
sin θ = ( mg / T)
θ = arc sin [( mg / T)]
The angle made by the string is calculated as follows;
θ = arc sin [( mg / T)]
θ = arc sin [( 0.019 x 9.8 / 0.22)]
θ = 57.8⁰
