The plates of a spherical capacitor have radii 6.25 cm and 15.0 crn. the space between the two spheres is filled with a material with dielectric constant of 4.8 calculate the capacitance. put your answer in the form of .abc x 100). f?

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
