Answer:
Explanation:
Due to first charge , electric field at origin will be oriented towards - ve of y axis.
magnitude
Ey = -8.99 x 10⁹ x 4.1 x 10⁻⁹ / 1.08² j
= - 31.6 j N/C
Due to second charge electric field at origin
= 8.99 x 10⁹ x 3.6 x 10⁻⁹ / 1.2²+ .6²
= 8.99 x 10⁹ x 3.6 x 10⁻⁹ / 1.8
= 18 N/C
It is making angle θ where
Tanθ = .6 / 1.2
= 26.55°
this field in vector form
= - 18 cos 26.55 i - 18 sin26.55 j
= - 16.10 i - 8.04 j
Total field
= - 16.10 i - 8.04 j + ( - 31.6 j )
= -16.1 i - 39.64 j .
Ex = - 16.1 i
Ey = - 39.64 j .
Answer:
At the point when an item is moved into the air toward a path other than straight up or down, the speed, quickening, and uprooting of the article don't all point a similar way. In circumstances like this, when taking care of the difficult we ought to apply the procedure of settling vectors into segments. At that point we apply the more straightforward one-dimensional types of the conditions for every segment. At long last, we can recombine the parts to decide the resultant.

Objects that are tossed or dispatched into the air and are dependent upon gravity are called projectiles. The way of a shot is a bend called parabola. In the event that an article has an underlying speed in some random time span, there will be level movement all through the trip of the shot.
Shot movement is free fall with an underlying speed. The underlying flat speed of a shot is equivalent to the level speed all through the shot's flight.
To discover the speed go a shot anytime during its flight, discover the vector aggregate of the parts of the speed now. We should utilize the Pythagorean hypothesis to discover the extent of the speed and the digression capacity to discover the course of the speed. On the off chance that an article has an underlying vertical part of speed and a level segment of speed, the item's movement ought to be settled into its segments, and afterward the sine and cosine capacities can be utilized to locate the vertical and even segments of the underlying speed. The speed of a shot dispatched at a point to the ground has both flat and vertical parts. The vertical movement is like that of an item that is hurled straight with an underlying speed.
Answer:
0 J
Explanation:
= Work done on the satellite in circular orbit about earth by earth
= Force on gravity on satellite by earth
= displacement of the satellite
= Angle between the force on gravity and displacement = 90
We know that, Work done is given as
