question_answer 1)

Where will the hour hand of a clock stop, if it starts (a) from 6 and turns through 1 right angle? (b) from 8 and turns through 2 right angles? (c) from 10 and turns through 3 right angles? (d) from 7 and turns through 2 straight angles?

Answer:

(a) It is clear from the figure, that the hour hand starts from 6 and turns through 1 right angle. Hence, it will be reach at 9. (b) It is clear from the figure, that the hour hand starts from 8 and turns through 2 right angles. Hence, it will be reach at 2. (c) It is clear from the figure, that the hour hand starts from 10 and turns through 3 right angles. Hence, it will be reach at 7. (d) It is clear from the figure, that the hour hand starts from 7 and turns through 2 straight angles. Hence, it will be reach at 7 because straight angles is equal to 4 right angles.
