A body weighs 22.42 g and has a measured volume of 4.7 cc The possible errors in the measurement of mass and volume are 0.01 g and cc. Then the maximum error percentage in the density will be
A) 22%
B) 2.2%
C) 0.22%
D) 0.022%
Correct Answer:
D
Solution :
A man moves 20 m north, then 10 m east and then \[10\sqrt{2}m\]south-west, then his displacement is AD. Then distance A to D = AD = 10m (north)
