35. A body of mass 'm' is moving with constant speed V on a track as shown in figure. At point A and point B radius of curvature is R. NA , NB and NC represents normal reactions at A, B and C. Which of the following is correct.

(i)  N A = m g - m V 2 R
(ii)  N B = m g + m V 2 R
(iii) NC = mg
(iv) All of these

Dear student,

Hence, the answer is (d) all the above.
Regards.
