well, there will be force on q1.....
because ....
the sphere and the the charge outside it will repel...........true
now as the sphere moves in -ve direction the charge inside it will not be symmetric................
so by method of images there will be force on the charge q !!!!!!!!!
u can even consider the system of say........
metallic sphere(sphere do not hve charge) has a charge inside it then also charge will expierence force..............
and it goes by the method of images..........
u can also use by electric field lines............
so my dear friend the charge will expiernce the force.......

and i knw u for last 1 yr nd so.......i thnk u need to go to psychiatrist
and ????????

u dont hve any oder issue in life man..........
hve u met or seen any one over here who r de any how is the person n al.......
aur yeh sab kya chalu hai .ill commit suicide bcoz here every1 make friend seeing ur alti........i mean r u so imature and ....i mean 1st april ko abhi time hai!!!!!!!!
in any case if u get into iit plzzz dont take any admission ova der.......u wont b able 2 live der!!!!!!!
??????????
and in any case its a forum to clear ur iit doubts and not 2 mke friends and solve ur stupid emotional issues....

get life broder..........

rco+ wen it is R3C-CO Cl then it gives R3C+

otherwise all other acid chloride gives d former electrophile

hm.sorry for late reply anyways..
take any general time "t" such dat angle rotated is

t

find the vel.. of point a ...which is WR

since the rod is rigid vel.. of a along the rod is same as the velocity of point B(attached to the block)

find the angle between the rod at b and the line joining the centre of the disc....

so vel of B=WR sin(90-Wt-Q)

since they hve given dat l >>> R

sinQ= rsinWt/l = tanQ = Q

so u get thew ans

phew!!!!!

so broder do u need d solution or not lemme knw!!

ma pleasure

ahh..ma scanner not working but still ill try to help...
tak a ray is incident on the drop and the refracted ray join dem and use the exterior angle thereom to find deviation ....likewise for reflected ray bcoz dats quite obvious dat of 180-2r and again wen ray emerges u join dem and find d deviation....

hope its clear....
ill postit in night .......wid diagram

(-10,0) multiply and divide by 5

deviation is given by i-r +i-r +180-2r

source ...its dc pandey i crossed checked it.....anyways if its challenge then its not worth it if its a dooubt then lemme knw ill post the solution

i dont want rates!:)

GUYS POST UR MARKS HOW MUCH UR GETTING

MINE IS 205

is it zero as i think induced electric field willl be perpendicular to each element of rod.....so induced emf will be zero....
not sure though!

MU^3/F

U

F

U.....is icross product.....and it is in modulus..

m-mass

u-velocity

f-force acting on it

....

there is also differential equation
