A car of mass `m_(1)` rests on a plank P of mass `m_(2)`. The plank rests on a smooth floor. The string and pulley are ideal. The car starts and moves towards the pulley with acceleration.

A

If `m_(1)gt m_(2)`, the string will remain under tension.

B

If `m_(1)lt m_(2)`, the string will become slack.

C

If `m_(1)=m_(2)`, the string will have no tension, and C and P will have accelerations of equal magnitude.

D

C and P will have acceleration of equal magnitude if `m_(1)ge m_(2)`.
