1. Question 2 1 pts A 2.0 kg ball is attached to a wall by a rope of negligible mass. A second rope
attached to the ball is pulled horizontally away from the wall with a force of 8.0 N as shown.
What angle does the first rope makes with the wall? 2.0 kg 8.0N A 57 B 44 C. 68 D. 22 O D
Question 3 1 pts In the above problem, what is the magnitude of the tension in the rope making
the angle e with the wall? A. 80N B. 12N C. 21N D. 28N
Solution
here,
mass , m = 2 kg
applied force , F = 8 N
let the tension in the string be T
equating the forces vertically
T * cos(theta) = m * g ...(1)
and
T * sin(theta) = F ...(2)
from (1) and (2)
tan(theta) = F/mg
theta = arctan(8/(2*9.81))
theta = 22 degree

2. the angle theta is D) 22 degree
