Question

) Two blocks of mass M, and M2 are connected with a string which passes over a smooth pulley. The mass
My is placed on a rough inclined plane as shown in the figure. The coefficient of friction between the
block and the inclined plane is . What should be the minimum mass m2 so that the block M, slides
upwards?
a) M2=M,( sine+ucose)
b) M2=M,( sine-ucose)
c) My - sino *ucos
cose
GEL
d) M
M
,
2 sine-ucosa​

Answer 1

Answer:

Since the coefficient of friction is not given for block m and M1, we will assume it to be frictionless.

Hence to stay under equilibrium, friction on bottom surface of M1, that is,
