Answer:
The surface gravity is inversely proportional to the square of the radius of the planet
Explanation:
The gravity at the surface of a planet is given by:
where
G is the gravitational constant
M is the mass of the planet
R is the radius of the planet
We see from the formula that the surface gravity is inversely proportional to the square of the radius of the planet, R.
At the Earth's surface, the value of the surface gravity is approximately 9.81 m/s^2.
Answer:
10581.59 V
Explanation:
We are given that
Magnetic field=B=0.65 T
Speed of electron=
Charge on electron,
Mass of electron,
We have to find the potential difference in volts required in the first part of the experiment to accelerate electrons.
Where V=Potential difference
Mass of electron
v=Velocity of electron
Using the formula
Hence, the potential difference=10581.59 V
