(a)

... help_outlineImage Transcriptionclose(a) Position of the particle, r = ( 4i + 6j): Force acting on it, F = (3i + 2j) N Torque on the particle about origin, T =r x F -(4i + 6i)<(si + 2j) = 8k – 18k T = -10k (b) Yes, there be another point about which the torque caused by this force on this parti cle will be in the opposite directi on and half as large in magnitude. (c) Yes, there can be more than one such points. (d) Yes, such a point can lie on the y axis. (e) No, more than one such point can not lie on the y axis. fullscreen
