Answer:
Kinetic energy of the electron
Explanation:
It is given that,
Initial speed of an electron, u = 660000 m/s
Final speed of the electron, v = 0 (at rest)
The kinetic energy of an electron is possessed due to the motion of an electron. The mathematical formula for the kinetic energy is given by :
m is the mass of electron
Since,
So, the initial kinetic energy of the electron is 1.23 eV. Hence, this is the required solution.
The object will stays the same.
80 because if you add 50 +30 =80 so yea that why I pick 80
Your answer is A
