% change/error in area/perimeter if length of edge is changed

% change/error in volume/area if length of edge is changed

If the rate of change of area of a square plate is equal to that of the rate of change of its perimeter, then length of the side, is

The percentage error in measurements of length and time period is 2% and 1% respectively . The percentage error in measurements of 'g' is

The measures of the length and breadth of a rectangle are (30pm3%) and (10.0pm0.5%) m. Calcualte the percentage error in the perimeter of the rectangle. [Hint : Perimeter = (length + breadth).]

In the experiment to determine Young's modulus of the material of a wire under tension used in the arrangement as shown. The percentage error in the measurement of length is a in the measurement of the radius of the wire is b and in the measurement of the change in length of the wire is c . Percentage error in the measurement of Young's modulus for a given load is
