Period = (1) / (frequency)
Period = (1) / (200 per second) = 0.005 second = 5 milliseconds
Sum of all forces = mass * acceleration
Ft= tension force
Fw= force of gravity (Fw= mass* acceleration of gravity which is 9.8 this only applies to force of gravity)
Ft- Fw = 0 (there is no acceleration)
Ft = Fw
Ft= m*g
Ft= 0.250kg*9.8m/s
Ft= 2.45N
Answer:
c
if you calculate the net force you get 490 N
