Question

If the distance of the points (2, -3) and (-8 ,-11) are equal from the point (k, -7), then the value of k is​

Answer 1

Step-by-step explanation:

=> same forces are acting in opposite directions

=> As K depends on the medium force will change if we place the system in other medium.

=> Let the distribution of charge is done as shown

Force between q

1

and q

2

F=

d

2

K(q

1

(Q−q

2

)

For force to be maximum

dq

1

dF

=0

So, this is the distribution of charge in which force is maximum.
