Question

7.
The force of attraction between two unlike magnetic polos varias inversely as the square
of distance between them. When the distance between two polos is 10 cm, the force or
attraction is 2 dynes. Find the force of attraction between the two polos when the distance
between them is 5 cm.​

Answer 1

distance between 2 poles = 10 cm

force = 2 dynes

initial distance = 5 cm

= 10/2*5

=1 dyne
