Question

Q.10. The blocks of masses m; = 6 kg and m2 = 7 kg are connected by a light string passing
over a light frictionless pulley as shown in fig. The mass mi is at rest on the inclined
plane and mass me hangs vertically. If the angle of incline 830°. What is the
magnitude and direction of the force of friction on the 6 kg block 7 (Take g = 10 cm)
m, 7 kg
30°​

Answer 1

Answer:

ANSWER

m

2

=6kg

T=6×10=60N

Force along plane, F

1

=mgsinθ=25N

Balancing forces along the plane;

∴T−mgsin30

0

−f=0

f=T−mgsin30

0

=60−25

=35 N
