Electro
force on shell and charge is same
first charge and shell will cover distance R/2 then charge is just inside shell , potential inside shell is 0 , acc is 0 they both travel with const Velocity for R distance , R by charge , R by shell
Distance travelled by Charge = R + R/2 = 3R/2 this is the answer and const velocity for R distance , this also the answer but
Pt of charge at start = KqQ/R and it wont just decrease linearly since shell is also moving , how will we find speed?...
Mechancis
from just intuition i understand why min acc of below ball and max acc of above ball will be what
but how do we solve the quesion for max speed and stuff?...
Organic
I over complicated this , i thought cuz of CIS there will be some hindrence in ans , but there was none , and sometimes when i dont apply CIS it is there in ans , how to know when to apply
Organic Chem
after the reaction there are 2 Br one at the place of OH and one where is it orignally , with AgBr shouldnt only the top Br go , the below one is aromatic why will it leave? but mam took that 2 Br will come from 1 mole of R
Hydrocarbons/organic, stability of carbocation
What makes A more stable than D? Isn't D aromatic while A is not?
conceptual lag in flux
according to gauss law flux through this random body should be q1/epsilon. q2 has no contribution in the flux since the electric field lines that enter the body also exit it thus flux is zero (source :https://youtu.be/ZR9pNx90YRU?si=QR84K-VpzGPqruSZ&t=3981)
Organic , Isomers
there was a question for counting no of structures , she counted both trans as seprate , why? both trans are the same if one is up and other is down why does it matter both groups are the same
pNc
wont ans be 6C4 x 4! x 4x3
first select 4 ppl , then arrange by 4! then the 2 ppl left have 4 and 3 choices
ans is 1080 by mine is coming out to be 4320...
Nucleus
i did after 1 hour particles left = 125 , decomposed = 875 , now 60% probability of alpha so 60% of alpha is 525 , i get the ans but is my method right or is it a coincidence i got the ans
Electrostats doubt- Field just below a hemispherical surface
Isn't the disc electric field formula applicable for this q? Derived by using solid angle. Could someone show their working? I have a couple of doubts.
