The Young’s modulus of polythene is 0.8
The answer is C.
they run east to west which makes them parallel to the equator and they measure distances north and south.
I hope this helps.
False, that does not apply to some
Answer:
Magnetic field = 0.534 T
Explanation:
The solving is on the attach document.
Answer:
Now e is due to the ring at a
So
We say
1/4πEo(ea/ a²+a²)^3/2
= 1/4πEo ea/2√2a³
So here E is faced towards the ring
Next is E due to a point at the centre
So
E² = 1/4πEo ( e/a²)
Finally we get the total
Et= E²-E
= e/4πEo(2√2-1/2√2)
So the direction here is away from the ring
