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.
Thank you and i hope it helps.
Answer:
120 Newton
Explanation:
Given the following data;
Mass = 12 kg
Angle = 4°
We know that acceleration due to gravity is equal to 10 m/s
To find the minimum force to stop the block from sliding;
Force = mgCos(d)
Where;
m is the mass of an object.
g is the acceleration due to gravity.
d is the angle of inclination (theta).
Substituting into the formula we have;
F = 12*10*Cos(4°)
F = 120 * 0.9976
F = 119.71 ≈ 120 Newton
