A) \[8.0A{{m}^{2}}\]
B) \[3\times {{10}^{-6}}C\]
C) \[6\times {{10}^{-3}}N\]
D) none of these
Correct Answer: B
Solution :
K.E. gained by the electron when accelerated to a potential difference of V volt = eV where v is the velocity acquired by electron Now \[4\times {{10}^{-4}}\] or \[1.07\times {{10}^{7}}m/s\] (Here: V = 200 volts, \[0.53\times {{10}^{7}}m/s\]) \[1.53\times {{10}^{7}}m/s\]You need to login to perform this action.
