Answer:
Explanation:
Given The side of a cubical block when measured with vernier calipers is 2.50 cm. the vernier constant is 0.01 CM. the maximum possible error is in the area of one face(in cm^2) is
We know that area of one side of cubical block
A = l^2
Now differentiating with respect to l we get
d A / dl = 2 l
d A = 2l dl
Δ A = 2 x 2.50 x 0.01 = 0.05
So maximum possible error is ± 0.05
