Answer» Solution :When a tankeraccelerates a PSEUDO force EXERTED on oil and hence its surface does not REMAIN horizontal . Consider a small ELEMENT of mass dm . The forces on it are shown as in figure . For equailibrium , the force parallel to the slope, `(dm)acostheta=(dm)gsintheta)` where the pseudo force exerted opposite to the acceleration (dm)a `thereforeacostheta=gsintheta` `thereforetantheta=(a)/(g)`=slope |
