Question

formula pressure on a square plate​

Answer 1

Explanation ⇒

% Error in Force = 4 %

% Error in Length = 2 %

Area of the Square Plate = (length)²

∴ % Error in Length in the area= = 2 × 2

= 4 %

Pressure = Force/Area

∴ % Error in Pressure = % Error in Force + % Error in Length in area

= 4 + 4

= 8 %

Hence, Option (d). is correct.
