Explanation:
When an moving electric charge passes through a uniform magnetic field
its motion becomes circular .
If m be the mass v be the velocity , q be the charge on the mass B be the magnetic field and R be the radius of circular path
force on the moving charge created by magnetic field
= B q v
Centripetal force required for circular motion
= m v² / R
For balancing
B q v = m v² / R
v = B q R / m
Time period of rotation
T = 2π R / v
= 2 π R m / B q R
= 2 π m / B q
For first particle
T₁ = 2 π m₁ / B q₁
For second particle
T₂ = 2 π m₂ / B q₂
q₁ = q₂ and 10 m₁ = m₂ ( given )
Putting the values in second equation
T₂ = 2 π 10 m₁ / B q₁
= 10 x 2 π m₁ / B q₁
= 10 T₁
Given T₁ = T
T₂ = 10 T
Solution :
Let the positive 
is along the East and the positive 
direction is along the north.
Given :
Mass of the Tesla car, 
= 
Mass of the Ford car, 
Now let the initial velocity of Tesla car in the south direction be = 
The initial momentum of Tesla car, 
Let the initial velocity of Ford car in the east direction be = 
So the initial momentum of the Ford car is 
Therefore, the initial velocity of both the cars is 
Now the final velocity of both the cars is 
So the vector form is :
Therefore the momentum after the accident is
According to the law of conservation of momentum, we know
From, 
We get, 
Therefore the speed of Tesla car before collision = 25.4 m/s
The speed of ford car before collision = 24.4 m/s
No, you can't see the equator.

i know cause i already learned this
