NO
At t=0, an ant is at(-1m.0m) & a spider is at (1m,0m). The ant starts walking counterclockwisealong the unit circle,& spider starts creeping to the right along the X-axis.
The ant"s horizontal speed is always half of the spider"s. The shotest distance between the ant & spider during their entire motion is
a)1m
b)√2 m
c)2m
d)√14/4 m

motion of ant wrt to spider is a circle... with center (-2,0)
min dist =2 m
how.. spider is moving towards right..
. wrt spider motion is circlle with center -2,0
oh!!!!!!!! spidy is goin right!!!!!!!!! DATZ Y I WAZ THINKIN HOW IT CAN BE 2m
see one of the spiders has a velocty along x axis as v
another spider will have a net velocity of v.. so the componnent along x axis will be less than v..
so the relative velocity will be mroe than v.. no matter which direction the spider is moving....
SO i think the distance can only increase.!
i think there is some problem in there initial positions ant should be at (1,0)and spider(-1,0)
otherwise there distance is always increaseing
why are the two v's same bhaiyya
ant"s horizontal speed is always half of the spider"s
so its actual speed can be any thing na?
why is the reply pinked i asked only a question
n what is the answer??????
