the correct options are (a) and (b)....

(1)

the scale reading is high when the elevator goes up with increasing speed that is upward acceleration.....

(2)

use the equation of motion.....

W^2=Wo^2+2a (theta)
where W=final angular velocity
Wo=initial angular velocity

W^2=0+2 (4)(10×2pi)
W^2=8(20pi)
W^2=160pi
W=(160pi)^0.5
W=22.4rad/s
