Explanation :
It is given that,
Side of square,
It is given that, the potential at point c is equal to zero.
So, potential at point a due to and is given as:
where,
So, (Since, is negative)
Hence, the potential at a due to and is equal to 0 V.
Explanation:
<h2>Interference is the example of soap bubble colouring</h2>
<h3>EXTRA INFO:</h3>
(LOOK AT THE IMAGE)
An incoming light ray is partly reflected by the top surface of the soap film and partly reflected by the bottom surface. The wave reflected from the bottom surface has traveled further (an extra distance equal to twice the thickness of the film) so emerges out of step with the top wave. When the two waves meet, they add together, and some colors are removed by destructive interference. Where the film is thickest, the bubble appears more blueish; where it's thinner, it will look more violet or magenta.
Answer:
Part a)
Final charge on C : q = 1.875
Part b)
Ratio for A = 6 : 1.25
Ratio for B = -1 : 1.875
Ratio for C = 0
Explanation:
When two identical metal sphere are connected together then the charge on them will get equally divided on both after connecting them by conducting wire
So here we have
Step 1: We connected A and B and then separate them
so we have
Step 2: We connected A and C and then separate them
so we have
Step 3: We connected B and C and then separate them
so we have
Answer:
it wont fly away
Explanation:
depending how tight the knott and find it is going to be stuck to the pole
Answer:
torch will not light up
Explanation:
because the torch itself need two but you placed one so it will not light up
