To have a force of 3.8x10-8 the two chaarges must be 0.65m apart.
Answer:
Explanation:
Given that:
The conductivity of the material = 5.0 s/m
; &
The electric field intensity of the material E = 250 sin(10¹⁰ t) V/m
(a) The conduction current density
(b) Displacement current density
Recall that:
∴
(c) The frequency at which will have the same magnitude is:
By substitution
f = 90 GHz
It will loose energy to the ground
It it will desrease in speed or velocity
Answer:
The Work Done is
Explanation:
Since , the equipment is pulled in horizontal horizontal plane.
Therefore, its normal reaction must be equal to its weight.
So, Normal reaction,
We know, frictional force ,
(Where N is Normal reaction and is coefficient of kinetic friction )
Therefore,
We know ,
( Here D is distance covered by the force)
Putting, D=1000 m.
We get , Work Done
