Suppose you want to determine the electric field in a certain region of space. You have a small object of known charge and an instrument that measures the magnitude and direction of the force exerted on the object by the electric field. (a) The object has a charge of +25.0 μC and the instrument indicates that the electric force exerted on it is 40.0 μN, due east. What are the magnitude and direction of the electric field? E = (b) What are the magnitude and direction of the electric field if the object has a charge of -10.0 μC and the instrument indicates that the force is 40.0 μN, due west? E = (Chp18,p13GO)

(a) 1.6 N/C, due east.

(b) 4 N/C, due east.

Explanation:

The force vector, on the charge, q, in the electric field vector, , is

Let the unit vector towards east is , so the unit vector towards west is -

(a) Given that:

,

, due east

From equation (i)

So, the magnitude of electric field is 1.6 N/C and the direction is towards east.

(b) Given that:

,

, due west

From equation (i)

So, the magnitude of electric field is 4 N/C and the direction is towards the east.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
