Joincharges
two small charges each of mass m kg and charge Q C are suspended from a position by a sphere of L meter of negligible mass. if theta is the angle between vertical postiton to the equilibrium has been reached
prove: q2 = 4mgL2sin2(theata)tan(theata)k
the 2's are square...
thermal conduction
how to solve this . i designed the question on my own inspired from infinite resistors ladder problems.
consider lower rods to be highly conductive . i.e zero thermal resistance
(like a wire in circuit)...

Rotational Motion
Shouldn't the acceleration of the bead on release be g as there is no other force acting on it?

diff btw vinylic and aryl
what is differnece between vinylic halide and aryl halide cuz we are saying we usesp2 of c=c in vinylic and sp2 in aromatic in aryl but cant the aromatic one come in vinylic also cuz i saw this

Increasing order of reactivity towards SN2 reaction
What is the answer? It should be 4 > 3 > 2 > 1 according to me as I is the strongest nucleophile, followed by Br, Cl and F

Degree of dissociation and association
we have been given a formula by our teacher about degree of association [ alpha=( i - 1)/(1/n-1) ] and dissociation [ alpha = (i - 1)/(n-1) ] but i dont understand where it comes from, its derivation im getting confused
Organic chem doubt from hydrocarbon/ alkyl halide
Shouldnt there be a 3rd case as well in which H radical is removed from the left most carbon (1st carbon acc. to IUPAC naming)

Waves basic doubt
I don't really understand how to distinguish between wt-kx and kx-wt. can we write (kx-wt+pi) as (wt-kx)? can someone pls help with this question. not very familiar with the conventions.

Organic Chem: Use of CsCO3
What is the use of CsCO3/MeI in this question? Also, can someone explain briefly where B and D go wrong?

Ray Optics, lateral shift through slab
I got as far as
shift = h sinr/cosr
, i.e. the first step in the second pic. But what is going on with i-r
lol how did the last step happen
Number of functions question
I did the question by making cases where f(x)=x or {f(x)=y,f(y)=x} or where connecting x to f(x) forms a closed cycle of 4. Does the given solution consider this? Or am I committing a flaw here?
