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
Answer:
More the mass, greater the inertia
So the greatest inertia will be possessed by C. 10 lb bag of potatoes

Answer:
let the age of elder sister = x+8
then let the age of younger sister be x
sum of their ages = 64
according to the question,
x+8+x = 64
2x+8 = 64
2x = 64-8
2x = 56
x = 56/ 2
x = 28
so, the age of younger sister is 28 years
and the age of elder sister is x+8= 28+8= 36years
It's a simple mechanism, used to change magnitude/vector of force
