Answer:
e = k q / r² then,
e = 9×10^9 * 1×10^-6 / 50² = 3.6 N/C
hope this helps ❤.
Answer:
T = 300 N
Explanation:
As we know that the painter is standing at the middle of the scaffold
So here the two ropes will exert same tension on the scaffold
So we will have

also we know

so we will have


so tension is half of the weight in both the strings
So it is
T = 300 N
ΒγΕ the answer should be a hot day
Because almost all of the force is done by the weight of the person and the mechanism of the swing itself, when you push someone you only give them an increase in velocity, the acceleration comes from the weight at first and then from gravity when the person is coming down, which is why we bend our legs when coming down
There are 3 significant figures, if that answers the question.
