Pressure at the place remains the same for both water and mercury.


Pressure exerted by mercury = density of mercury * height of mercury column * g (acc. due to gravity)


=> Pressure exerted by mercury = 13.6 * 70 * g

=> Pressure exerted by mercury = 952 g.


Pressure exerted by water = density of water * height of water column * g (acc. due to gravity)


=> Pressure exerted by water = 1 * h *g

=> Pressure exerted by water = h g.


Now, According to question,


952* g = h* g

=> h = 952 cm.


Therefore, the height of water column which will exert on its base the same pressure as the 70 cm column of mercury is 952 cm. (Answer)
