Explain why When a small drop of detergent is placed on water, the needle moves rapidly away from it and sinks when more detergent is added.(Assume that the detergent does not affect the density of water)

When soap is added to the water, the needle will be driven to sink by the disruption of the water's surface tension.

step-by-step explanation:

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
