Two charges lie on positive x-axis. Charge A (2.0 x 10-9 C) is 2.0 cm from the origin and Charge B is 4.0 cm from the origin. (-3.0 x 10-9 C). What is the total force exerted by these two charges on Charge C (5.0 x 10-9 C) located at the origin?
A turbine operates under steady flow conditions, receiving steam at the following state: Pressure
1.5 MPa, temperature 185 degree C, enthalpy 2785 kJ/kg, velocity 33.3 m/s and elevation 3 m.
The steam leaves the turbine at the following state: Pressure 22 kPa, enthalpy 2512 kJ/kg, velocity
100 m/s, and elevation 0 m. Heat is lost to the surroundings at the rate of 0.29 kJ/s. If the rate of
steam flow through the turbine is 0.42 kg/s, what is the power output of the turbine in kW?
(a) Consider a dipole in which a Point (𝑃) is located inline with
+ive charge as shown in below F
the formula for electric field intensity (𝐸⃗ ) at point 𝑃.
(b) How the formula will change if 𝑃 is far away from the +ive
charge.
(c) How do you relate the formula obtained in part (b) with that we
have derived in class in which 𝑃 is present vertically above at
the axis of the dipole.
(a) Let’s consider a two-dimensional (2-D) disk on which +ive charge is uniformly
distributed as shown in below figure. Derive the expression for 𝐸⃗ at point 𝑃 due
to this charged disc
