Answer
option B
38 N
Explanation
Given that,
mass of block A = 14kg
mass of block B = 12kg
angle alpha equals = 19°
Formula to find tension in the wire connecting blocks A and B
Tension in wire connecting weight of object A and B is due to weight of block B
= mgsin19
due to slope we will take horizontal components of weight, mg
= 12(9.81)sin(19)
= 38.3
