Explanation:
From the question we are told that
The radius of curvature is
Generally the radius of curvature is mathematically represented as
Here is the focal length hence
=>
=>
This question can be solved using the concept of the composition of the vector.
(a) The magnitude of F is b "164.27 N".
(b) The angle of the vector from horizontal is " ".
(a)
From the composition of the rectangular components of a vector, we know that the magnitude of the resultant vector is given by the following formula:
where,
= x-component of the force = 122 N
= y-component of the force = 110 N
Therefore,
<u>F = 164.27 N</u>
(b)
The angle of the vector is given by the following formula:
<u>θ = 42.04°</u>
