Answer:
D (not so sure, look in the explanation and judge yourself)
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards
Minimum force required = 0.25 x 34 x 9.81
= 83.385 N
So technically the force need to be greater than 83.385 so the answer should be d, not really sure if it should be b though really depends on the acceleration due to gravity.
Explanation:
r^2= 9×10^9 × 5.87×5.87×10^-16 / 64.9
=47.7× 10^-8
so taking sq. root
r = 6.9 ×10^-4 m
or
r= 6.9×10^ -2 cm
this gives the required seperation
A wave that moves up and down
