Question

Block A has a mass of 14 kg, block B has a mass of 12 kg, and angle alpha equals 19°. What is the tension in the wire that connects blocks A and B?
44 N

38 N

33 N

41 N

Answer 1

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
