A smooth cone is rotated with an angular velocity ' \( \omega \) ' as shown. A block \( A \) is placed at height \( h \). Block has no motion relative to cone. Choose the correct
\( \mathrm{P} \)
options, when \( \omega \) is increased.
(1) Net force acting on block will increase
(2) Normal reaction acting on block will increase
(3) \( h \) will increase
(4) Normal reaction will remain unchanged
