A) virtual enlarged image
B) no image
C) a real inverted image
D) a real enlarged image
Correct Answer: C
Solution :
\[R\propto \frac{1}{t}\] \[t=\]average time interval between two successive collision of electrons. When switched on, temperature of filament increases, there by K.E. of \[\bar{e}\] increases which increases the velocity of electron Hence time interval (t) between two collision decreases, hence R increases.You need to login to perform this action.
