Electrostatics: Finding force experienced by charge

AI Thread Summary
To find the force experienced by a 3 microcoulomb charge, the aggregate force from other charges must be calculated using vector addition. The user successfully determined the triangle's sides using the Pythagorean theorem but struggles to find the angle theta at point P for the resultant vector. Trigonometry is suggested as the method to calculate the angle, specifically using the known sides of the right-angled triangle. Clarifications on the user's understanding of trigonometry are requested to facilitate further assistance. Mastery of these concepts is essential for solving the problem accurately.

1. Find the magnitude and direction of the force experienced by the charge of 3microcoulombs.

Homework Equations


After subtending forces of both the particles on the third one, we need to find the aggregate magnitude of the charge experienced by it.

The Attempt at a Solution


I was able to find all the sides of the triangle created using using the Pythagoras theorem but am not able to find the angle theta at point P to find the magnitude of the resultant Vector. That should be it right? Thanks.[/B]

You have a right angled triangle with all the sides known.
You can find ∠APO using elementary trigonometry.
Have you studied trigonometry?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
