Answer:
he same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem
Explanation:
When there are several applied forces, if they are all in the same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem, so which the resulting dowry is less than the sum of the magnitudes.
Let's carry out an example with two forces, F1 and F2 of equal magnitudes
if they are in the same direction
F_total = F₁ + F₂ = 2 F
if they are at 90º
F_total =
if they are at 180º
F_total = F₁ -F₂ = 0
Answer:
The reading on the ammeter A₁ , should be 2 Amp.
Explanation:
Given circuit shows all the bulbs are connected in parallel and ammeter A(T) at the source reads 6 Amp.
So, as the bulbs are in parallel connection, the current gets divided equal to each bulb.
so, the reading on the ammeter A₁ , should be 2 Amp.
But it will show 6 Amp, which is three times of the required value(2 amp).
This is because there was a mistake while making the circuit connections.
Instead of making connections as given circuit, the connections were made different as uploaded circuit.
Instead of connecting ammeter A₁ to only one bulb, it is connected to all the bulbs.
To correct this, remove the wire connecting ammeter and the second bulb.
And connect the second bulb directly to the switch.
