A beaker containing a liquid of density `rho` moves up with an acceleration `a`. The pressure due to the liquid at a depth h below the free surface of the liquid is.

Options

A. ` h rho g `
B. `h rho (g + a ) `
C. ` h rho (g - a ) `
D. ` 2 h rho g `

Answer

B

Explanation

Effective gravity ` g _ (eff ) = g + a `
` P = rho (g + a ) h`
