Answer:
20 cm to the right of the center or 20+50 = 70 cm from the left side.
Explanation:
The length of meter stick is 1 m = 100 cm
Balance point on 50 cm
From the center the 20 N weight is 50-20 = 30 cm
Torque is obtained when force is multiplied with the distance
As the force is conserved we have
The distance will be 20 cm to the right of the center or 20+50 = 70 cm from the left side.
Question is incomplete. Missing part:
Find the charge on the capacitor at the following times:
1) t = 0 mu S
2) t = 1 mu S
3) t = 50 mu S
1)
We start by calculating the initial charge on the capacitor. For this, we can use the following relationship:
where
C is the capacitance
Q0 is the initial charge stored
V0 is the initial potential difference across the capacitor
When the capacitor is connected to the battery, we have:
Solving for ,
So, when the battery is disconnected, this is the charge on the capacitor at time t = 0.
2)
To find the charge on the capacitor at any other time t, we use the equation:
where
t is the time
is the resistance
is the capacitance
Therefore, at time , we have:
3)
As before, we use again the equation:
However, here the time to consider is
Substituting into the formula,
