It's gotta be purple!!!!!!!!!!!!!!!
Answer:
Explanation:
A ) The spheres are non conducting , charge will not move on the surface so neutralization of charge by + ve and - ve charge is not possible. Charges will remain intact on them . The electric field inside them will be zero . Electric field outside shell will not be spherically symmetrical . Lines of force will emanate from the surface of positively charged shell outwardly oriented and end at negatively charged shell .
B )
distance between the centres of spherical shell
= 2 a
potential energy of charges
= k q₁ x q₂ / R
= k x - Q x Q / ( 2a )
= - k Q²/ 2a
So work needed to separate them to infinity will be equal to
= k Q²/ 2a
Shield volcanos have the most predictable eruptions.
Answer:
Part b)
Explanation:
magnetic field due to external source is given as
area of the loop is given as
Now we have
now we need to find the time at which voltage is 0.1 Volts so we have
Part b)
If magnetic field is inclined at an angle of 30 degree with the normal of the loop then
now we know that induced EMF is given as
