An open tank `10 m` long and `2 m` deep is filled up to `1.5 m` height of oil of specific gravity `0.82`. The tank is uniformly accelerated along its length from rest to a speed of `20 m//s` horizontally. The shortest time in which the speed may be attained without spilling any oil is

A

20 sec

B

18 sec

C

10 sec

D

5 sec

Text Solution

Verified by Experts

The correct Answer is:
A
`v=u+a_(x)t, a_(x)=v/t`
` tan theta=(a_(x))/g=v/(tg) =0.5/5` (in triangle ABC)
`rArr t=(10xx20)/10=20 sec`
