Suppose you have three identical metal spheres, a, b, and c initially sphere a carries a charge q and the others are uncharged. sphere a is brou contact and separated. finally spheres a and c are brought in contact and then separated.

The charge on sphere A and C is

Solution:

As per the question:

Charge on sphere A = q C

Now,

When sphere A with 'q' charge is brought in contact with B then conduction takes place and equal charges are distributed on both the spheres as:

Charge on each A and B is

Now, after separating both the spheres, when sphere B with charge touches uncharged sphere C, again conduction occurs and the charge is distributed as:

Now, after the charges are separated with charge on each sphere B and C

Now,

When sphere A and Sphere C with charge and comes in contact with each other, conduction takes place and charge distribution is given as:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
