Answer:
24.71 mm
Explanation:
Distance is proportional to focal length, so
d∝f
which means
Magnification of first lens
and
Similarly, magnification of second lens
and
From the above equations we get
and
which means,
and
So, we get
∴ Focal length should this camera's lens is 24.71 mm
If you look at a em spectrum you see that it’s X-rays while radio waves have the least
Answer:
The magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
Explanation:
Given:
Velocity of proton
Magnetic force N
Charge of proton C
The magnetic force experience by proton in magnetic field is given by,
Here magnetic force experienced by proton is maximum so we take
T
According to the left hand rule the direction of magnetic field is out of the page.
Therefore, the magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
