Hope this helps you
Last option 3000N
Given:
R1 = 130 m
R2 = 65 m
w^2R = g
Assume, g = 9.81 m/s^2
w^2 = 9.81/130
w = 0.275 rad/s
At R2 = 65 m
g = w^2R
= (0.275^2) × 65
= 4.905 m/s^2
In conclusion,
g × R = k
g1/R1 = g2/R2
g2 = (g1 × 65)/130
= g1 ×1/2
= g1/2
what is the answers? i cant help you without the answers
