Question

The value of ‘g’ at a particular point is 9.8 m/s2 Suppose K the earth suddenly shrinks uniformly to half its present size without losing any mass The value of ‘g’ at the same point from the centre of earth does not shrink) will now be :

  1. 4.9 m/sec2    
  2. 3.1m/sec2    
  3. 9.8 m/sec2    
  4. 19.6 m/sec2    

The correct answer is: 9.8 m/sec2
