39. Figure below shows the electric field lines for two point charges separated by a small distance. (a) Determine the ratio q1byq2 (b) What are the signs of q1 and q2?
Answers
Where is the figure bro.....
But I hope this will helps you
number of electric field lines is proprtional to the magnitude of charge
since lines are moving out from charge q2 it is positive
and lines are moving in the charge q1 , it is positive
(a) so q1/q2 = -1/2
(b) q2 = positive charge
q1 = negative charge
Hope it helps you
Thank you❤
Answer:
To determine the ratio q1/q2, we can use the fact that the electric field lines around point charges always point radially outward from a positive charge and radially inward towards a negative charge. If we assume that the two point charges have opposite signs, then the electric field lines between them will be directed from the positive charge towards the negative charge.
The ratio of the magnitudes of the electric charges q1 and q2 can be determined by counting the number of electric field lines originating from each charge. The charge with more electric field lines is the one with the larger magnitude. If there are n1 electric field lines originating from charge q1 and n2 electric field lines originating from charge q2, then we have:
q1/q2 = n2/n1
To determine the signs of q1 and q2, we can use the fact that electric charges of the same sign repel each other, while charges of opposite sign attract each other. If the electric field lines between the two point charges are directed from a positive charge towards a negative charge, then we can conclude that q1 is positive and q2 is negative.
In summary, to determine the ratio q1/q2 and the signs of q1 and q2 based on the electric field lines for two point charges separated by a small distance, we need to count the number of electric field lines originating from each charge and determine the direction of the electric field lines between the charges. If the electric field lines are directed from a positive charge towards a negative charge, then q1 is positive and q2 is negative, and we can use the ratio of the number of electric field lines to determine the ratio of the magnitudes of the charges.
