11a,b,c,d
a certain mirror placed at the origin has i^ as the normal vector to its reflecting surface. the mirror begins to translate with a velocity i^ +j^ +k^ at t=0, at the same time an object which was initially at i^+j^ starts movng with a vel (i^+j^) m/s.
now choose thecorrect option(s) :- [multiple choice]
a) initial postion of the image will be -i+j
b) vel of image will b i+j
c) vel of image relative to the object will be zero.
d) velocity of the image raletive to the mirror will be -k^.

1yeah mee too jus imagined
so don ask for solutn [4][4]
i will giv it after sm time
11vmirror = i^ + j^ + k^
vobj = i^ + j^
So, w.r.t obj. mirror is only moving along k^ , and hence b,c,d are correct(a is obvious).
1i dont Khow How you all did it, but i tried taking two axes as i^ + j^ and k^...................... Howzzzzzzzat ?
1thnx krish n vishal... i meade the mistake of not visualising and starting to solve it :'(
now i jus visualised as u all did n told .. n got widn 1 min.. :'(
