At what height is an object that has a mass of 50kg, if its gravitational
potential energy is 9800j?

H=20 rounded to the ones

H=19.9 rounded to the tenths

H=19.97 rounded to the hundredths  

Explanation:

Its Qu 13) On Worksheet: Kinetic and

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
