What is the escape speed of an electron launched from the surface of a 1.0-cm-diameter glass sphere that has been charged to?
Answer:
To calculate the escape speed of an electron launched from the surface of a charged glass sphere, we need to consider the electric potential energy and the kinetic energy of the electron.
First, let’s calculate the electric potential energy. We know that the electric potential energy can be given by the equation:
PE = q * V
where PE is the potential energy, q is the charge on the electron, and V is the potential difference.
In this case, the sphere has been charged, so it has an electric potential difference. However, the diameter of the sphere is given, but we need to know the charge on the sphere to calculate the potential difference accurately.
Once we calculate the potential difference, we can then proceed to calculate the escape speed. The escape speed is the minimum speed required for an electron to escape the electric field of the charged sphere.
The kinetic energy (KE) of an electron is given by the equation:
KE = (1/2) * m * v^2
where m is the mass of the electron and v is its speed.
To find the escape speed, we equate the electric potential energy to the kinetic energy:
q * V = (1/2) * m * v^2
From this equation, we can solve for v, which will give us the escape speed.
However, without knowing the charge on the glass sphere, it is not possible to calculate the escape speed accurately. Therefore, we need more information to provide an exact value for the escape speed.
