Answer:
Coefficient of friction will be 0.296
Explanation:
We have given initial speed of the stone u = 8 m /sec
It comes to rest so final speed v = 0 m /sec
Distance traveled before coming to rest s = 11 m
According to third equation of motion
So
Acceleration due to gravity
We know that acceleration is given by
So
So coefficient of friction will be 0.296
(a) Equivalent capacitance of network between points a and b is 2.3μF.
(b) Charge on each of the three capacitors nearest a and b is 920 μC.
A) Let's consider the right side that is farthest from the point 'a'.
Three C1 are connected in series
C= 1/C1 + 1/C1 +1/C1 = C1/3
C = 6.9/3 = 2.3μF
Now this C is connected in parallel with C2
So, C= 2.3 + 4.6 = 6.9μF
Again we get three capacitors of 6.9μF each, connected in series.
C = C1/3 = 2.3μF
It again combines with 4.6μF in parallel
C = 4.6 + 2.3 =6.9μF
Now, this final reduction is the same as that of the first.
In the end, we have 3 capacitors of 6.9μF each connected in series.
Equivalent Capacitance C(eq) = C1/3 = 6.9/3 = 2.3μF
= 2.3 × F
B) C(eq) = 2.3 × F
Vab = 400 V (Given)
Charge on each of the three capacitors nearest a and b (Q) =?
Q = C(eq) × Vab
= 2.3 × × 400 = 9.2 ×
C = 920μC
Hence, the equivalent capacitance of the network between points a and b is 2.3μF.
And Charge on each of the three capacitors nearest a and b is 920 μC.
