Question

An object of mass $m=2.5 \mathrm{g}$ and charge $Q=+42 \mu \mathrm{C}$ is attached to a string and placed in a uniform electric field that is inclined at In angle of $30.0^{\circ}$ with the horizontal (FIGURE $19-50 ) .$ The object is in static equilibrium when the string is horizontal. Find (a) the magnitude of the electric field and (b) the tension in the string.

Step 1

The electric field at point P is given by: E = qv/r = (42 \mu \mathrm{C})(2.5 \mathrm{g})/(300 \mathrm{N/m})(0.3) = 1.5 \mathrm{N/m} Show more…
