Sorry ,next I'll take care of it.
For part b) Tension is calculated from equation of motion of mass m2. N in part a) mu R=m1gcostheta.
Reply its correct answer pls. ma'am
Since no perpendicular motion of mass m1 ,therefore equation :
R=m1g cos35 no applied.
Now, equation of motion of m1:
m1f=T-m1 g sin35 .
Equation of motion of m2:
m2f= m2g -T .
Adding the two equations,
(m1+m2)f=( m11 - m2sin35)*g
Rearranging,
f=m1-m2sin35*g divided by m1+m2.
Here f is...
