Answer:
Where the electric potential is constant, the strength of the electric field is zero.
Explanation:
As a test charge moves in a given direction, the rate of change of the electric potential of the charge gives the potential gradient whose negative value is the same as the value of the electric field. In other words, the negative of the slope or gradient of electric potential (V) in a direction, say x, gives the electric field (Eₓ) in that direction. i.e
Eₓ = - dV / dx ----------(i)
From equation (i) above, if electric potential (V) is constant, then the differential (which is the electric field) gives zero.
<em>Therefore, a constant electric potential means that electric field is zero.</em>
Answer:
v = 418.31 m/s
Explanation:
given,
Radius of earth = 6400 Km
latitude at Miami, Florida = 26°
first we have to find the radius of the rotation at that latitude.
radius = 6400 x 1000 x cos 26°
circumference will be equal to = 2 π r
cos θ is used because at equator angle is zero radius is maximum and cos θ is maximum at 0°
calculation of time to
time = 24 hr
t = 24 x 60 x 60 = 86400 s
v = 418.31 m/s
speed of a physics student in Miami, Florida is equal to v = 418.31 m/s
