Sodium Hypophosphate is

NaH₂PO₂-H₂O.

Rate me if you find this info useful.

The negative charge which comes after removal of H is not satble as electron density is increased by +I effect of methyl groups.

Rate me if you find this info useful.

In a balanced wheatstone bridge, galvanometer shows zero deflection. That's how the working of wheatstone bridge is explained. As the 2 points joining galvan. are equipotential hence no current flows through galvanometer.

Don't forget to rate me.

Hey its really easy,

A and D are connected be conducting wires, so they are at same potential. SO we have to find p.d. between A and B. ACB=60 ohm.

therefore 2v is across 60ohm.

Therefore across 30ohm, pd=2/2=1V. as pd changes in series and is devided in the ratio of resistances. as both resistances here are equal therefore half pd will be there across each resistance.

Don't forget to rate me.

I don't think its such a daring ques.

No doubt that the charges will move in the presence of a force.

But electrostats deals with that force which 2 charged particles exert on each other when initially at rest.

Hi

Its a good question. I am getting 0.222 A as answer. Plz check if it is correct, then I will send you the solution.
