<span>here we have to apply the right hand rule
no, since the magnetic field is perpendicular with respect to the direction of the current</span>
Hello!!
For this, we only need frequency and speed, so for calculate we applicate formula:









The moon does not have an atmosphere because it is not a planet. It is just a big lump of rock that has a core. It was created from the Earth.
Option (B) is correct.The magnetic field strength=8.5 x 10² T
Explanation:
the magnetic force Fm is given by
Fm= q V B sinθ
q= charge=1.4 x 10⁻⁷ C
v= velocity= 1.3 x 10⁶ m/s
B= magnetic field strength
Fm= magnetic force= 1.5 x 10² N
θ=75°
so 1.5 x 10²=(1.4 x 10⁻⁷) (1.3 x 10⁶ ) (B) sin75
B=8.5 x 10² T
The large can of solids will reach before the empty can reason being is it has more additional weight its like dropping a 1 pound weight compared to a 4 pound the 4 pound reaches faster because of the gravitational pull the size of the pull depends on the masses of the objects
