Answer:

A. #102900 N#

Explanation:

Here,the water is filled in a cylinder and volume
#(v)# occupied by it is #l×A# i.e #7×1.5 m^3# or #10.5 m^3#

So,its weight #(w)# will be #m×g# where,#m# is its mass and #g# is acceleration due to gravity.

Now,#m=rho×v# where, #rho# = #1000 (Kg)/m^3#

So,#w = (1000×10.5×9.8) N# or, #102900 N#
