The coordinates of a particle of mass `'m'` as function of time are given by `x=x_(0)+a_(1) cos(omegat)` and `y=y_(0)+a_(2)sin(omega_(2)t)`. The torque on particle about origin at time `t=0` is :
If two independent waves are y_(1)=a_(1)sin omega_(1) and y_(2)=a_(2) sin omega_(2)t then
A particle of mass 0.2 kg moves along a path given by the relation : vec(r)=2cos omegat hat(i)+3 sin omegat hat(j) . Then he torque on the particle about the origin is :
