Each capacitor carry the same charge 'q'.
Discussion:
The voltage from the battery is distributed equally across all of the capacitors when they are linked in series. The three identical capacitors' combined voltage is computed as follows:
= V₁ +V₂ +V₃
This voltage may also be calculated using capacitance and charge;
V = Q/ C
= V₁ +V₂ +V₃
Provided that the total charge is 'q', hence the total voltage can be expressed as:
= (Q/C₁) + (Q/C₂) + (Q/C₃) = Q(1/C₁ +1/C₂ +1/C₃)
Therefore from the above explanation, it is concluded that each and every capacitor carry same charge 'q'.

Answer:
(a) Total time = 105.5 sec
(b)average speed = 31.26 m/sec
Explanation:
We have given that three-wheeled car starts from rest that initial velocity u = 0 m/sec
Final velocity = 35 m/sec
Acceleration
According to first law of motion we know that v = u+at
So
t = 17.5 sec
After this car travels 83 sec at a constant speed and after that it takes 5 sec additional time to stop
(a) So total time in which car is in motion = 17.5+83+5 = 105.5 sec
(b) Total distance traveled during first 17.5 sec
Distance traveled in 83 sec with with velocity of 35 m/sec =
For next 5 second
Initial velocity u = 35 m/sec
Final velocity = 0 as finally car stops
So
Distance traveled
So total distance traveled = 306.25+2905+87.5 = 3298.75 m
Total time = 105.5 sec
So average speed
