A very thin glass rod 4 m long is rubbed all over with a silk cloth (see figure below). It gains a uniformly distributed charge +4.2 × 10-6 C. Two small spherical rubber balloons of radius 1.2 cm are rubbed all over with wool. They each gain a uniformly distributed charge of -6.7 x 10-8 C. The balloons are near the midpoint of the glass rod, with their centers 3 cm from the rod. The balloons are 2 cm apart (4.4 cm between centers). Length 4 m (drawing not to scale) 2 cm ¡ 3 cm Radius 1.2 cm 0.6 cm Part 1 (a) Find the magnitude of the electric field at the location marked by the x, 0.6 cm to the right of the center of the left balloon. i N/C Also calculate the angle the electric field makes with the horizontal.

Question
A very thin glass rod 4 m long is rubbed all over with a silk cloth (see figure below). It gains a uniformly distributed charge +4.2 x 10-6 C. Two small spherical rubber balloons of radius 1.2 cm are rubbed all over with wool. They each gain a uniformly distributed charge of -6.7 x 10-8 C. The balloons are near the midpoint of the glass rod, with their centers 3 cm from the rod. The balloons are 2 cm apart (4.4 cm between centers). Length 4 m (drawing not to scale) 2 cm --- 3 cm Radius 1.2 cm 0.6 cm Part 1 (a) Find the magnitude of the electric field at the location marked by the x, 0.6 cm to the right of the center of the left balloon. i N/C Also calculate the angle the electric field makes with the horizontal. (Take the horizontal to be the +x axis pointing to the right.) i counterclockwise from the +x axis.
