Gravity only determines the path in projectile motion
Answer:
1.8 mV
Explanation:
The total number of turns in the solenoid is
where
n = 6500 is the number of turns per meter of length
is the length of the solenoid
The flux linkage through the solenoid is given by
where
B is the strength of the magnetic field
is the cross-sectional area of the solenoid
The strength of the field in the solenoid is given by
where I is the current.
At the beginning, I = 0, so the field is
And the flux linkage is
Later, the current is I = 1.5 A, so the field in the solenoid is
So, the flux linkage is
So, the change in flux linkage is
And therefore, the emf induced in the solenoid is (in magnitude)
Answer with Explanation:
We are given that
x=-2.6 cm to x=2.6 cm
Linear charge density=
Length of wire=
Length of wire=
1 m=100 cm
We know that
a.Linear charge density=
Where Total charge =Q
Length=L
Total charge,Q=
Using the formula
Total charge,Q=
b.y=4 cm=
1 m=100 cm
Electric field on the y-axis is given by
Using the formula
c.y=12 cm=
Using the formula
