Time taken by each ion to travel the semicircular path through the magnetic field is 34 X 10⁻²⁶s.
<u>Explanation:</u>
Given:
Charge of oxygen ion, q = -2
Magnetic Field, B = 0.12 T
Mass of O₂ , m= 2.6 X 10⁻²⁶ Kg
Time, T = ?
We know,
Therefore,
T = 2 X 3.14 X 2.6 X 10⁻²⁶/ 2 X 0.12
T = 68 X 10⁻²⁶s
For semicircular orbit, Time taken would be T/2
T ₓ = 68 X 10⁻²⁶/2 s
T ₓ = 34 X 10⁻²⁶s
Therefore, time taken by each ion to travel the semicircular path through the magnetic field is 34 X 10⁻²⁶s.
Answer:
255.61 m
Explanation:
Use 
in downwards direction from the moment of flight till the car hits the bottom.
As the car fly off the cliff the velocity of the car in vertical direction will be zero.
This statement about the potential due to the sphere is correct: THE POTENTIAL IS HIGHEST AT THE CENTER OF THE SPHERE.
The potential is highest at the center of the sphere because, charge usually flow from the region of higher potential to lower potential.
It affects basketball in a way called traction.
The friction between the players' basketball shoes and the hard wooden floor is traction, or friction. Without it, players would slide everywhere and wouldn't be able to play the game.
