Concept explainers
The tension in the wire which is used to hang the mirror.
Explanation of Solution
Given information:
A
Calculations:
Here we draw a schematic diagram of the situation.
Here point A to B is attached to the mirror and makes an angle of
Therefore gravitational force is acting downward.
Now we draw the force diagram
Now from the force diagram in point O,
Now total force acting on the wire is,
Therefore,
Therefore tension in AO is
Tension in BO is
