Answer:
a
When
b
When
Explanation:
From the question we are told that
The radius is R
The current is I
The distance from the center
Ampere's law is mathematically represented as
When
=>
But when
The magnitude of displacement =
the distance between start-point and end-point,
regardless of the route followed along the way.
Any motion that ends up where it started has zero displacement.
An object on a circular path starts over at zero displacement every time
it completes a full revolution. So does a race-car on a track.
Answer:
Force of friction is 10 N.
Explanation:
Given:
Mass of the table is,
Force acting towards right,
Net acceleration of the table,
Let the force of friction acting on the table to the left be N.
Therefore, net force acting on the table is given as,
Now, as per Newton's second law of motion,
Equating the above two equations, we get
Therefore, the magnitude of the force of friction acting on the table is 10 N to the left direction.
