Since f=m(v^2/r),or fnet is equal to ma.
force = unknown
velocity=22m/s
radius=75m
f=m(v^2/r)
f=925(22^2/75)
f=5969.333N
20/40=0.5 g/cm^3 becuase, mass/volume=density.
Answer:
Explanation:
Given
Charge Q is spread over non conducting sheet
Electric field due to sheet is
where
Now if the sheet is stretch to becomes length
thus the ratio of new and initial electric field is
