What is centripental force?
1 answer:
Answer:
Centripetal force is the force that is necessary to keep an object moving in a curved path and that is directed inward towards the center of rotation.
Explanation:
Definition of centripetal force:
Centripetal force is the force that is necessary to keep an object moving in a curved path and that is directed inward towards the center of rotation.
Example of centripetal force
A string on the end of which a stone is whirled about exerts a centripetal force on the stone.
The diagram is shown below
Where
The centripetal forces acting towards the centre C that is
and the direction is from A to C.
And the stone is moving in a circular motion with center as C.

Answer:
The magnitude of electron acceleration is
Explanation:
Given:
Distance from the wire to the field point m
Speed of electron
Current A
For finding the acceleration,
First find the magnetic field due to wire,
Where
T
The magnetic force exerted on the electron passing through straight wire,
N
From the newton's second law
Where mass of electron
kg
So acceleration is given by,
Therefore, the magnitude of electron acceleration is
