an eq (Asub "r")^x=1     r=1 to k     this eq has  "m" real roots

 another eq(x-a sub"r")^101=0   r=1to k   this eq has" n "real roots

 then find the relation b/w "m" and "n"

         need full concept of sol nickles assured

ans is v/2

 I THINK SO THAT CONSTANT FUNCTIONARE NOT PERIODIC IF U DIS AGREE ME PLZ EXPLAIN ME FROM GRAPH

sir i m unable to understand why centre of sphere and plank got different acceleration when there is no sliding b/w them            help me

sir both sphere and plank has different acceleration

sorry challenge is already down the list

 a plank of mass M1 with a uniform sphere of mass M2 placed on it rests on a smooth horizontal plane . Aconstant horizontal force F is applied to the plank .With what aceleration will the plank and the centre of the sphere move provided there is no sliding b/w the plank and sphere  

ok then solve it ans is cos=3gl/2w^2 

since it is a rod and not

the thread                      

with a pendulun

u cant use the concept of tension

a conic pendulum ,athin uniform rod of lenth L and mass M,rotates uniformly about a vertical axis with angular velocity(w) the upper end of the rod is hinged .find the angle  b/w the rod and the vertical
