A block of mass m slides m slides down a smooth incline of angle of inclination `theta`. The force acting on it are N (normal reaction). And mg (weight). The accelration of the block is `alpha`. Two students analyze the situation and apply Newton a second law. `{:("First student","Second student"),(mg sin theta=ma,mg-Ncos theta=ma sin theta):}`

A

Only first student is correct

B

Only second student is correct
