Explanation:
Image distance (Di) = 17 cm
Object distance (Do) = 36 cm
Using mirror equation,
1/Di + 1/Do = 1/f
1/17 + 1/36 = 1/f
0.058824 + 0.027777 = 1/f
1/f = 0.086601
f= 11.5472 = 11.55 cm
Kinetic energy of electron is gained by the potential energy that it is getting through the potential applied across it
now here we know that that
charge that is accelerated is an electron
so we will have
here we know that
so kinetic energy will be same as potential energy which is equal to
