Referring to Example 19−6 Suppose the magnitude of the electric field is adjusted to give a tension of 0.253 N in the thread. This will also change the angle the thread makes with the vertical. (a) Find the new value of E. (b) Find the new angle between the thread and the vertical.

Solution 110IP

Step 1 of 4</p>

Referring to the given example, we need to calculate the new electric field and the new angle the thread makes with vertical axis.

The magnitude of the tension in the thread is given to be . The given object has the charge with mass .

Given data,

To find,

Electric field, Angle,Step 2 of 4</p>

(a)

Here we need to calculate the electric field,

The horizontal component of forces on the object can be written as,

Using electrostatic force as

Squaring both sides,

…………...1

The vertical component of forces on the object can be written as,

Using weight as ,

……………….2

Squaring both sides,

…………...3

Adding equation 1 and 3,
