Question

the error in the measurement of the radius of a sphere is 0.4. find the percentage error in the surface area​

Answer 1

Answer:

percentage error= (least count of the instrument / reading)*100

therefore in p6

we use a spherometer to find the radius of a sphere, so the least count of spherometer is 0.01mm

therefore to find the percentage error divide (0.01/0.4)100

the answer is 2.5%
