To solve this problem it is necessary to apply the concepts related to the electric field according to the definition of Coulomb's law.
The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point.
Mathematically this can be described as:

Where,
permittivity of free space
r = Distance
q = Charge
E = Electric Field
Our values are given as,



Replacing we have,




Therefore the amoun of charge on the outer surface of the larger shell is 
Newton's first law of motion is connected with inertia :)
Answer:
ice melting
Explanation:
Because once it melts you can change it back to ice.
Refer to the diagram shown below.
The component of the applied force perpendicular to the door is
F * sin(60°) = 0.866F N
Because the moment arm is 0.40 m, the torque is
(0.866F N)*(0.4 m) = 0.3464F N-m
This torque is equal to 1.4 N-m, therefore
0.3464F = 1.4
F = 4.04 N
Answer: 4.04 N
Answer with Explanation:
We are given that
Restoring force,


We have to find the work must you do to compress this spring 15 cm.
Using 1 m=100 cm
Work done=
W=
