you should provide the options for us to answer?
Radius of curvature<span> of a spherical mirror = 2 × </span>Focal length<span>
and the ray of light is parallel to the principle axis if the incident </span><span>Passes through focus
therefore, focal length =30/2=<span>15cm
</span></span><span>The mirror should be placed at a distance of 15cm from the light bulb to produce this parallel light beam.</span>
Answer: The period of the pendulum is shorter if the pendulum itself is shortened.
Explanation: i did "It will depend on the bob’s mass". and got it wrong so it's not that one haha

Answer:
Explanation:
Field by negative charge will be more as net force due to both the charges is in positive y - direction.
field by negative charge at origin
= 9 x 10⁹ x 34 x 10⁻⁶ / .18²
= 9.45 x 10⁶ N /C
field by positive charge at origin
= 9 x 10⁹ x Q / .33²
= 82644.63 x 10⁶ Q N /C
Net field
= 9.45 x 10⁶ - 82644.63 x 10⁶ Q
force on charge 8.1 x 10⁻⁶ C
( 9.45 x 10⁶ - 82644.63 x 10⁶ Q ) X 8.1 x 10⁻⁶ = 31
76.545 - 669421.5 Q = 31
669421.5 Q = 45.545
Q = 45.545 / 669421.5
= 68 X 10⁻⁶ C
= 68 μC
