Physics P42 Discussion

[pakiboy]

Guyz lets discuss the paper as 24 hours have passed

 

[pakiboy]

were you able to do angular displacement question?

I was able to do it but i dont know its correct or not

 

[pakiboy]

i used tantheta to find the diameter, do you think its right?

Why tantheta?

 

[irtaza ali]

Also discuss other answers .

 

[TANJIAHOU]

angular displacement x seperation between planets = diameter

 

[Fares]

can you guys please atleast say what came in the paper?

 

[Mufasa]

there is no A* at inividual component level -_-

 

[nightmaressana]

Um, how were we supposed to calculate the diameter?

But bro this formula gives the arc length

 

[pakiboy]

What you guyz wrote about the student suggestion
And how you made the graphsin that question?

 

[pakiboy]

I know
the poll question says including previous may/june session!

 

[TANJIAHOU]

Small angle approximation. Why did u think they asked us to define the radian and give us the angular diaplacement in radians? Whether u used the trigonometry method or circular method, the answer WILL be the same. You can verify it yourself

 

[TANJIAHOU]

What you guyz wrote about the student suggestion
And how you made the graphsin that question?

Bad suggestion. Student did not move coil to cut the flux lines. So no induced emf for calculation of magnetic flux density

Can you send me a diagram of what you did

But the coil was moving bro, it was taken away from the straight conductor
I wrote that voltmeter was connected in series so bad suggestion can it be correct?

 

[TANJIAHOU]

He measured when it was held in position haha.

 

[TANJIAHOU]

There's no need to. You ask your teacher. He/she will explain how to do it.

Voltmeter was connected in series, so bad suggestion. Hmm... My teachers always connect voltmeter across the coil.

 

[pakiboy]

Voltmeter was connected in series, so bad suggestion. Hmm... I thought galvnometers are high resistance voltmeters?

It wasnt a galvanometer it was millivoltmeter and voltmeters have also high resistance
