The minimum horizontal acceleration of the container a so that pressure at the point A of the container becomes atmospheric is (The tank is of sufficient height)

Options

A. ` (3)/(2) g `
B. ` (4 )/(3) g `
C. ` (4 ) /(2) g `
D. ` (3)/(4) g `

Answer

B

Explanation

Volume equality gives
` rArr 2 xx 3 = (1)/(2) xx h xx 3 rArr h = 4 m `

` rArr tan theta = ( 4 )/(3) = (a)/(g) rArr a = (4)/(3) g `
