Question

If the coefficient of passive earth pressure is 1/3, then the coefficient of active earth pressure is

Answer 1

we know that
coefficient of active earth pressure=1/passive earth pressure
we are given that
Kp=1/3
now Ka=1/Kp
Ka=3

Answer 2

The coefficient of active earth pressure$,K_{a}=3$

Step-by-step explanation:

Given,

The coefficient of passive earth pressure($K_{p}$) = $\dfrac{1}{3}$

To find, the coefficient of active earth pressure$(K_{a})=?$

We know that,

The relation between $K_{p}$ and $K_{a}$,

$K_{p}\times K_{a}=1$

⇒ $\dfrac{1}{3} \times K_{a}=1$

⇒ $K_{a}=3$

∴$K_{a}=3$

The coefficient of active earth pressure$,K_{a}=3$

Hence, the coefficient of active earth pressure$,K_{a}=3$
