Answer:
Gravity Increases - Mass increases, distance decreases
Gravity Decreaes - Mass decreases, distance increases
Answer:
The electric field is
Explanation:
From the question we are told that
The radius of the inner sphere is
The radius of the outer sphere is
The charge on the inner sphere is
The charge on the outer sphere is
The position from the origin is
Generally the electric field is mathematically represented as
The reason for using for the calculation is due to the fact that the position considered is greater than the but less than
Here k is the Coulomb constant with value
So
Assuming both billiard balls have the same mass, conservation of momentum says
where m = mass of both billiard balls, and v₁ and v₂ = their initial velocities, and v₁' and v₂' = their final velocities. The masses are the same so the exact value of m is irrelevant. The first ball has initial speed 5 m/s and the second is at rest, so
After the collision, the first ball has speed 4.35 m/s and is moving at angle of 30° below the original path, so
Then the second ball has final velocity vector
so it moves with speed
at an angle of
or about 60.5° above the original line of motion.
Answer:
Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 =
at oher surface is ∈_2=
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2
A model train traveling at a constant speed around a circular track has a constant velocity. FALSE.
Hope this helps you!
