Earth around the sun and the moon around the earth
Answer:
Explanation:
The relationship between electric field strength and potential difference is:
where
E is the electric field strength
V is the potential difference
d is the distance between the plates
Here we have
V = 218 V
d = 1.29 cm = 0.0129 m
So, the electric field is
Answer:
Explanation:
We are given that
Current,I=2.85 A
Length of segment=l=2.35 m
d=0.275 m
We have to find the magnitude of magnetic field due to this segment of wire at a point P which is at midpoint of the straight wire.
Magnetic field,B=
Where
Using the formula
Momentum... spins on a tilted axis....
