Angular accelaration force,as the result of the rotatation of earth
Arzoodan
Due to the rotation of the earth the winds at the equator get deflected in opposite direction and therefore cause some currents in the Northern and Southern hemisphere which are opposite in there spin.

∇(f/g) = (g∇f − f∇g)/g^2
, at points x where g(x) 6= 0 please help me to solve the problem ....
sir please add answer sheet of spigel vector analysis ..
In a pulley system 2 boxes r hanging in both sides of pulley. An other box was joined to the left box through a rope & get accelerated downward. If all the boxes have same mass ,then what will be the acceleration of that system ?
∇(f/g) = (g∇f − f∇g)/g2
, at points x where g(x) 6= 0 plus solve it
