Question

a body weight 5N is placed on a wooden table.how much force is required to set it into motion?co efficient of friction between the table and the body is 0.3​

Answer 1

Answer:

Answer is A

Explanation:

The 2 rightmost nodes are shorted-circuit due to the conductive wire.

Then 6 Ohm - 4 Ohm set and 7 Ohm - 3 Ohm sets are individually in parallel arrangment.

Therefore, the equivalent of 6 Ohm- 4 Ohm set is

And that of 7 Ohm - 3 Ohm set is

Finally, both these equivalents are in a series arrangement. Therefore, the equivalent resistance between AB is
