What happens if an opaque object is placed in the path of light? a) light bends when it hits the object. b) light does not pass through the object. c) light completely reverses its direction. d) light pierces the object and continues to travel.

The correct option is B.

Explanation:

An opaque objects are those object which does not allow light to pass through them. It blocks the path of light.

For example, wood.

When an opaque object is placed in the path of light then light does not pass through the object.

Light continue travels in a straight path until it bounces off the ground. Then, it will form a shadow.

Therefore, the correct option is B.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
