Answer:
D is correct.
The upward force on the ball must be the same at both locations:
F = M a = 0 = F(upwards) - F(downwards)
If the ball is not being accelerated the upward force must equal the downward force on the ball.
Answer:
as we find the resultant of the magnetic field we get in the xy plane. Just perpendicular to this plane i.e. along z-axis the charge is moving. Hence the force acting on the charge will also be in the xy plane.
Net field = ./(0.078^2 +0.070^2) = 0.105 T
Angle with x axis is arc tan 0.070/0.072 = 44.2 deg
So the force acting on the moving charge is got by Bqv
0.105*5.5*10^-5 * 6*10^3 = 0.03465 N
So the angle inclined by this force with x axis will be 90+44.2 = 134.2

The vertical component is = vsinx m/s
If you know the angle, substitute the value of x.
If you know the velocity at which it is moving, substitute it for v
Hope it helps :)
Answer:
The Event Horizon Telescope comprises of a an interconnection of radio observatories. These radio observatories work in unison and helps in efficient observation of radio sources associated with black holes with angular resolution in comparison to their event horizons. This equipment functions by ensuring that anything or light which goes through the event horizon cannot escape from the black hole. Instead there will be a continual falling towards the center of the black hole.
