Question

30points man!..solve it quickly to get 30point + brainlist​

Answer 1

tension = sum of centrietal force+gravity

notice these are vectors.

tensionvertical= mg down

tensionhorizonal= m w^2 * rad

= .5*(2PI/.4)^2 * .8

now, after calculating that, you add them as vectors

tension= sqrt ( (mg)^2+(horizonalabove)^2 )
