Calculate the electric field (in V/m) between two parallel plates connected to a 45 V battery if the plates are separated by a)

Sonja [21]

Answer:

Explanation:

Given

Voltage of battery $V=45\ V$

electric field(E) is given by

$E=|-\frac{dV}{dx}|$

i.e. Change in Potential over a distance x

(a)When Plate are separated by 3 cm apart

$E=|\frac{45}{3\times 10^{-2}}|$

$E=1500\ V/m$

(b)When Plates are 5 cm apart

$E=|-\frac{45}{5\times 10^{-2}}|$

$E=900\ V/m$

Force on electron is given by

$F=charge\times Electric\ Field$

$F=q\times E$

For case a

$F=1.6\times 10^{-19}\times 1500$

$F=24\times 10^{-17}\ N$

(b) $F=1.6\times 10^{-19}\times 900=14.4\times 10^{-17}\ N$

Frame S' passes frame S in the usual way (positive directions). An object also moves in the positive direction. Which is true? T

lisov135 [29]

Answer:

The answer is "The object's speed relative to S can be greater than or less than its speed relative to S', depending on the actual values."

Explanation:

The S' frame and the object are moving in a positive direction. The object is moving with respect to the S frame so the S frame the rest frame

take the velocity of the object with respect to the rest frame as v and the velocity of the S' frame with respect S frame as v2

relative velocity of the object to the S' frame would be

Vrel = v2- v

This means the Vrel of the object with respect to the S' frame is less than the Vrel of the object with respect to the S frame

However is the S' velocity is greater than that of the object then the Vrel of the object with respect to the S' frame is greater than the Vrel of the object with respect to the S frame.

This would mean the second option is the answer, the relative speed of the object depends on the actual values.
