Solve full question for me.from 4 cos sqr x
U kno cos sqr x= (1+ cos2x)/2
4(1+ cos2x)/2
2(1+ cos2x) this is wat they are saying

Thank you. So using that I got,from 4 cos sqr x
U kno cos sqr x= (1+ cos2x)/2
4(1+ cos2x)/2
2(1+ cos2x) this is wat they are saying
i)
resolve the forces
R (normal reaction)= 5sin30
friction +5cos30= 6
friction=1.67 N
ii)
F= mew (R)
mew = F/R
=1.67/5sin30
= 0.68
coz its in the same direction as the forcewhy friction is added, I am refering to the first part?
The direction shuld be against the movement of the ring, but it is not.coz its in the same direction as the force
The ring is sliding down due to force of gravity (Rings weight pulling it down) hence friction would be up hence it is added.The direction shuld be against the movement of the ring, but it is not.
friction is upward w.r.t weight whch is downward.The direction shuld be against the movement of the ring, but it is not.
The ring is sliding down due to force of gravity (Rings weight pulling it down) hence friction would be up hence it is added.
see..since the system is in equilibrium...means upward = downward na?The direction shuld be against the movement of the ring, but it is not.
