The answer to this question is
As we know that accelartion is the rate of change of velocity. So, it can be write as
where
is the final velocity
is the initial velocity
t is the time
a is the accelartion
as we konw
t = ?
From rest So,
= 0
Putting values
So, the right answe is
Answer:
1) Yes the direction of the magnetic field is found based on Fleming's Right Hand Rule
2) The pattern indicates the direction of the magnetic force field lines
Explanation:
1) The solenoid is the is the coil of electric conductor that when it carries an electric current produces a magnetic field
According to Fleming's Right Hand Rule, the direction of the magnetic field produced by a solenoid, depends on the direction of the current such that when the direction of the conventional current is in the direction of the wrapped fingers, the thumb points in the direction of the magnetic field which is North N.
2) The pattern of field lines inside the solenoid indicates the direction of the generated magnetic field moving from left to right within the solenoid as the electric current moves around in the direction shown in the diagram.
