A spherical tank of radius 0.35m is half filled with oil of relative density 0.8. if the tank is moving with a horizontal acceleration of `10(m)/(s^(2))`. The surface of oil is at rest with respect to sphere. The maximum gauge pressure of oil in the tank is `nxx10^(3)Pa`, the value of n is approximately equal to (take `g=10(m)/(s^(2))`
