Answer:
b. The electric field points away from the source charge, if the source charge is positive
d. The electric field points toward the source charge, if the source charge is negative.
Explanation:
A positive source charge would create an electric field that would exert a repulsive effect upon a positive test charge. Thus, the electric field vector would always be directed away from positively charged objects. On the other hand, a positive test charge would be attracted to a negative source charge. Therefore, electric field vectors are always directed towards negatively charged object.
Also electric field strength depends only on test charge
The correct options include b and d
The electric field points away from the source charge, if the source charge is positive.
Also, the electric field points toward the source charge, if the source charge is negative.
Hey, Name's Jessy. I hope, I answer your question.
Nearly 400 lbs,by 11.73%.
Kinetic energy of the rock just before it hits the ground=KE=33000 J
Explanation:
Weight= 2200N
mg=2200
m(9.8)=2200
m=224.5 kg
initial velocity=0
final velocity =V
using kinematic equation V²=Vi²+2gh
V²=0+2 (9.8)(15)
V=17.1 m/s
now kinetic energy= 1/2 mV²
KE= 1/2 (224.5)(17.1)²
KE=33000 J
Thus the kinetic energy of the rock just before it hits the ground=33000 J
