Mass m1moves on a slope making an angle ...

Mass `m_1`moves on a slope making an angle `theta` with the horizontal and is attached to mass `m_2` by a string passing over a frictionless pulley as shown in the figre. The co-efficient of frition between `m_1` and the slopping surfaace is `mu`. Which of the following statements are true?

A

if `m_2gtm_1 sin theta`, the boyd will move up the plane.

B

If `m__2gtm_1` (sin theta + mu cos theta)`, the boyd will move up the plane

C

If `m_2 lt m_1(sin theta + mu cos theta)`, the body will move up the plane.

D

If `m_2 lt m_1(sin theta - mu cos theta)`, the body will move down the plane.
