a. -6.17 rad

Explanation:

60 seconds is 2π radians.  Writing a proportion:

2π / 60 = x / 59

x = 6.17

The displacement is negative because the second hand moves clockwise.

The angular displacement of the second hand on a clock after 59 second is -6.17 rad.

Option A

Explanation:

As we know angular displacement is defined as the change in the displacement in a circular motion for a given angle. So, angular displacement is derived using the formula

Also, in a clock the second hand travel a distance of 2π in 1 minute. If for 60 s, the angular displacement is 2π. Then for 1 s, the angular displacement will be

And for 59 seconds, the angular displacement will be

As we do not know the displacement of seconds hand after 59 seconds but the angular displacement will be having a negative sign as the clock hands move in clockwise direction.  So ,
