Question

what horizontal force applied to it would keep the string at thirty degrees to the vertical​

Answer 1

Answer:

be the initial position of string and a mass suspended at the ene (A) be displaced at an angle

from its vertical position by the horizontal force

= mg=003 xx 9.8 N

OCB

F/(OC) = (ng0/(OC) = T/(BO)

F = mg x (CB)/ (OC) = (0.03 xx 9.80 xx tan 30^@

= 0.03 xx 9.8 xx 1 //sqrt3 N = 0. 16 94 N

=0.03 xx 1 // sqrt 3 kfg = 0 .01732 kgf
