Explanation:
The torque of a force is given by:
where
F is the magnitude of the force
d is the distance between the point of application of the force and the centre of rotation of the system
is the angle between the direction of the force and d
In this problem, we have:
, the force
, the distance of application of the force from the centre (0,0)
, the angle between the direction of the force and a
Therefore, the torque is
Answer:
Series equivalent resistance:
Parallel equivalent resistance:
Explanation:
The equivalent resistance in series circuit is calculated as
The equivalent resistance in parallel circuit is calculated as
Which can be simplified to
The parallel circuit has the higher equivalent resistance as compared to series circuit.
