Answer:
h=20.38 m
Explanation:
Given that
Initial speed of object u = 20 m/s
Acceleration
We know that
Here acceleration and velocity is in opposite direction so the object will come rest after reaching at distance h.When body will reach at its highest position then velocity will become zero(v=0).
Now by putting the values
h=20.38 m
Answer:
1.86 × 10 ∧-3 V/m
≅ 1.9 × 10 ∧-3 V/m
Explanation:
Radius of long solenoid (R)= 3 cm
Turns per meter (n) = 2500
current flowing in coil (I) = 0.30 sin (200 t)
Time (t) = 2.5 ms
Distance at which electric field calculated (r) = 4 cm
The main solution is shown in the picture attached below.
