In certain region of space with volume 0.2 `m^3` the electric potential is found to be 5V throughout. The magnitude of electric field is this region is

A

Zero

B

0.5 N / C

C

1N / C

D

5 N / C

Text Solution

Verified by Experts

The correct Answer is:
A
Since, electric potential is found throughout constant hence electric field, `E = -(dV)/(dr) = 0`

In a certain 0.1 m^(3) of space, electric potential is found to be 5 V throughout. What is the electric field in this region ?

Electric potential at any point V=-4x+3y+5z then magnitude of electric field in the space will be

In a certain region of space the electric potential V is known to be constant. Is the electric field in this region (a) positive (b) zero ,or (c ) negative ?

It is known that there exists a uniform electric field in a certain region. Imagine an incline plane (figure) in the region which is inclined at theta=37^(@) to the horizontal when one moves horizontally along the incline from A to B (AB=1cm), the electric potential decreases by 10V. Similarly, potential at C(AC=1cm) is less than potential at A by 10 V where line AC lies on the incline and is perpendicualr to AB. When one moves vertically up from point A to a point D(AD=1cm), the potential drop by 10 V again. Find the magnitude of the electric field in the region and the angle that it makes with vertical [given sin37^(@)=(3)/(5) ]

Electric potential at any point is V = - 5 x + 3y + sqrt(15) z , then the magnitude of the electric field is

In a certain region of space, the electric field is zero. From this, we can conclude that the electric potential in this region is:

In a certain region of space, the potential field depends on x and y-coordinates as V=(-x^2+y^2) . The corresponding electric field lines in xy-plane are correctly represented by
