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)
