Consider thre : blocks A, B and C. Block A is placed on block B, which is placed on block C
\( P \) and block C is placed on the ground. Normal W reaction between blocks \( \mathrm{B} \) and \( \mathrm{C} \) is three times of that between blocks \( \mathrm{A} \) and \( \mathrm{B} \). Normal reaction between block \( \mathrm{C} \) and ground is two times of that of between blocks B and C. Possible values of the masses of blocks \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) respectively are
(1) \( 5 \mathrm{~kg}, 15 \mathrm{~kg} \) and \( 10 \mathrm{~kg} \)
(2) \( 5 \mathrm{~kg}, 10 \mathrm{~kg} \) and \( 15 \mathrm{~kg} \)
(3) \( 5 \mathrm{~kg}, 15 \mathrm{~kg} \) and \( 30 \mathrm{~kg} \)
(4) \( 5 \mathrm{~kg}, 30 \mathrm{~kg} \) and \( 60 \mathrm{~kg} \)
