A person on the second floor takes the elevator up 5 floors, crosses to the other side of the building then takes the elevator on that side down by 2. The height of each floor is 3.5 m and the width of the building is 21 m. What is the person's displacement?

i think they are all correct

explanation:

they seem good

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
