a =
Part B
For what downward acceleration does the spring scale in (Figure 1) read zero if the experiment were done on the Moon?
Express your answer to two significant digits and include the appropriate units.
a =
Part C
How would your conclusion about the spring forces change if the brick were hung from the spring scale rather than supported by it?
How would your conclusion about the spring forces change if the brick were hung from the spring scale rather than supported by it?
a =
Explanation / Answer
a) the spring scale would read zero if it is accelerating downwards with an acceleration equal to acceleration due to gravity =9.8m/s2
b) acceleration due to gravity on surface of moon is 1/6 th that on earth
so on moon it should move down with an acceleration of 1.63 m/s2
c) the answer would not be effected
