A rectangular tank filled with some liquid is accelerated along a horizontal surface at (40)/(3)ms^(-2) . Inside the liquid, a laser pointer is fixed a the centre of the tank which shoots a thin laser beam in the vertically upward direction. If after refraction from the liquid surface, the laser beam moves along the surface of the liquid, then what is the refrctive index of the liquid ?
