Is it a I-V one or a R-V one?
I guess r-v, i drew an r-v graph
8. Nd numbr 6?

Not hard but I got confused in the 7th question. what was the answer for the 4th part?

What was the value of the gradient and of viscosity?
I got an an answer in millions. I was too late to realize that I didn't converted the mm to m.

what graph is to be sketched in question 7?
I stated that it is V against I , but my friends said that it's V against R. not sure which is correct

Nd numbr 6?
It's an easy question. Guess I've done it correctly.

i made a mistake also a very weird one....i converted by multiplying by 10^-9 instead of 10^-6
