Question
Weight of a body on the surface of the earth is W₁.
The weight of the same body is W2, at a height of 500 metres above the surface, and W3 at a depth of 500 metres below the surface of the earth. Which one of the following is the correct relation? Directions : Each of the following five items consists of a word in capital letters, followed by four words or groups of words. Select the word or group of words that is most similar in meaning to the word in capital letters.Solution
The Weight of an object is given by multiplying its mass (m) and acceleration due to gravity (g) as W=mxg. • The value of g varies with altitude in an inverse manner and as the altitude increases the value of g decreases and as altitude (height) decreases, the value of g increases. • Thus, W3>W2>W1 is the correct sequence.
