Answer:
Resistance in the flash tube,
Explanation:
It is given that,
Speed of the bullet, v = 500 m/s
Distance between one RC constant, d = 1 mm = 0.001 m
Capacitance,
The time constant of RC circuit is given by :
R is the resistance in the flash tube
..........(1)
Speed of the bullet is given by total distance divided by total time taken as :
Equation (1) becomes :
So, the resistance in the flash tube is . Hence, this is the required solution.
