Hi, today we are solving the question in which vector field is given by f is equals to zI which means f is equals to z 0 0. Now the surface S is oriented as shown in the figure I is e given by double integral over S f into dS. So here to determine the sign of I we need to consider the dot product f into dS. Since f is equals to z 0 and 0 the dot product will be positive. The dot product of f into dS is equals to positive when the x component of dS is positive and negative when the x component of the dS is negative and 0 when the x…
