The direction of an electric field is determined from the behavior of a positive test charge that is set free in the electric field.This charge moves along a distinct vector showing the direction of the electric field Therefore the answer is b. a positive charge will move in the field.
They have thick body coverings
Answer:
The correct answer is "4.26 m".
Explanation:
Given:
Wavelength,
or,
Distance,
or,
Distance between the 1st and 2nd dark fringes,
As we know,
⇒ 
or,
⇒ 
By substituting the values, we get
19-? Is the exact p.d across the 114-?resistor.
Current will different
But p.d will same in parallel circuit .
