But , No not always . For a concave mirrror the diameter of the image becomes 2 f theta.Hey friend, perhaps this information would help-'area of the image is pie x r square and is proportional to 2f.'

O.K. I will keep that in mind.

O.K.Thats great man.But what is 'Master = 315624'.

Dear guys and guls! What is the electric field produced by a uniformly polarised ring of radius R?? Please give me the final answer. I want to verify my answer.

Use binomial expansion of (0 + x) to the power -1.

Rays from the sun subtend an angle theta (in radians) at the pole of a convex mirror (in radians) at the pole of a mirror of focal length f. If the diameter of the sun is D ,then diameter of the image of the sun formed by the mirror is: (a) f theta (b) 2 f theta (c) 6 f theta (d) none...

But some of my friends solve this type of question within seconds.They seem to have a particular kind of trick.Well,they don't tell me.

O.K.I will try that.Werg22 , Please give me the final answer so that I can verify it.

A long cylindrical shell of radius R carries a uniform surface charge sigma naught on the upper half and an opposite charge - (minus) sigma naught on the lower half .What is the electric potential inside and outside the cylinder?

Yes you can say that.

OK ! Thanks Reshma .I will keep that in mind from now on.

Rank of a word means at which position it is written in the dictionary. Rank of a word is nothing but the arrangement of the given letters of the word in dictionary..order n finding after how many words which r possible by these letters our favourable word occurs...let me xplain wisd a...

Hey guys ! Is there any shortcut to find the rank of a particular word ?? If there is any, then what is it?

Ziox,You are right about your point on euclidean plane.I have not yet thought about that.But buddy, (b) is the intercept form of a line which cuts off intercepts a and b from x and y-axis respectively.Have you tried the (a) part ?

Werg22 and tim_lou thanks.But guys! I have already tried those techniques but I have not got an accurate to the point answer.As Werg22 says I am getting an ugly expansion of no significance.I am still far away from getting a simplified answer.Tim_lou, if you are getting a simplified answer then...
