4/9
9/4
2/9
2/7

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Uniform Circular Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Centrifugal Force act radially outwards,

So, N A = mg - mv²/R = m(10) - m(2)²/2= 8m

So, N B = mg + mv²/R = m(10) +m(4)²/2= 18m

N A : N B = 4 : 9
