Ex 5.2, 7 Where will the hour hand of a clock stop if it starts (d) from 7 and turns through 2 straight angles? We know that 1 straight angle = 1/2 of revolution = 1/2 × 12 hours = 6 hours We start from 7, and move 1 straight angle (12 hours) to 1 We start from 7, and move 1 straight angle (12 hours) to 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
This implies it will stop at \[2\] on clock.
This implies it will stop at \[7\] on clock.
This implies it will stop at \[7\] on clock.
Note: Angle made by the hour hand in \[1\] hour is \[30\]. Angle made by the minute hand of a clock in \[1\] minute is \[6\]. Angle made by the second hand of the clock in \[1\] second is also\[6\]. The angle measured in the clock is always measured clockwise by default unless it is mentioned in any particular direction. However the angle measured in a clockwise direction is taken as a negative angle in trigonometry and slope concepts.
