The owner of a physics bookstore owner hangs a sign board with a mass 8.4 kg in front of his shop. The pole is light weight and its weight can be ignored The cable used to support the board is tied to the beam at the end and also at the wall. The pole is free to about the end where it touches the wall, as shown in(Figure. 1) What is the tension in the cable? Express your answer to two significant figures and include the appropriate points,

Solution

Tension in the Cable is T = mg * cos theta = 8.4*9.8* cos 60

T = 8.4*9.8*cos 60 = 41.16 N
