In RLC circuit the frequency of the circuit is also known as resonance frequency of the circuit
It is calculated by

now for the maximum value of the capacitance we will use minimum frequency as they depends inversely on each other



Now for minimum value of the capacitance



So above is the values of maximum and minimum capacitance
Answer:
16.46 seconds.
13.46 seconds
2.67 m/s²
Explanation:
Acceleration = a = 1.35 m/s²
Final velocity = v = 80 km/h = 
Initial velocity = u = 0
Equation of motion

Time taken to accelerate to top speed is 16.46 seconds.
Acceleration = a = -1.65 m/s²
Initial velocity = u = 80 km/h= 
Final velocity = v = 0

Time taken to stop the train from top speed is 13.46 seconds
Initial velocity = u = 80 km/h= 
Time taken = t = 8.3 s
Final velocity = v = 0

Emergency deceleration is 2.67 m/s²
Peak voltage is 2
period is 40ms
frequency = 1/period = 25Hz
