Answer:
Explanation:
Given
Wooden board is pivoted at center and
Older child of mass is sitting at a distance of L from center
if two child of mass is sitting at a distance
and
(say) from pivot then net torque about pivot is zero
i.e.
as
Therefore
Therefore another child is sitting at a distance of
Given that,
Voltage = 10 volt
Suppose, The three resistance is connected in parallel and each resistance is 12 Ω. find the current in the electric circuit.
We need to calculate the equivalent resistance
Using formula of parallel
Put the value into the formula
We need to calculate the current in the circuit
Using ohm's law
Where, V = voltage
R = resistance
Put the value into the formula
Hence, The current in the circuit is 2.5 A
