Answer:
d = 1.636 m
Explanation:
Initially charged sphere are far apart so their potential energy is zero . Kinetic energy will be of small sphere
K E of small sphere
= 1/2 m v²
= .5 x 3.1 x 10⁻³ x ( 5.6)²
=48.608 x 10⁻³ J
If d be the distance of closest approach between them , potential energy of
Charges
= k q₁ x q₂ / d²
=
Total kinetic energy at this point will be zero.
Applying the theory of conservation of mechanical energy
Potential energy at distance d = Kinetic energy at infinity
48.608 x 10⁻³ =
d = 1.636 m
Density = Mass/Volume
2.5 g/ml = 5g/Volume
Volume = 5g/(2.5 g/ml)
= 2 ml
It's called Electrophily, or electron affinity.

Answer:
2.28 cm
Explanation:
Radius of the proton if v and B is perpendicular will be,
Now,
mass of proton, .
Radius of the orbit, .
Magnetic field, .
Charge on the proton, .
Now substitute all the variables in r.
.
.
Therefore the radius of the orbit of moving proton is 2.28 cm.
