Previous Question: A series R-C combination is connected to an AC voltage of angular frequency w = 500 radian/s. If the impedance of the R-C circuit is R sqrt(1.25) , the time constant (in millisecond) of the circuit is Next Question: A train is moving along a straight line with a constant acceleration ‘a’. A boy standing in the train throws a ball forward with a speed of 10 m/s, at an angle of 60° to the horizontal. The boy has to move forward by 1.15 m inside the train to catch the ball back at the initial height. The acceleration of the train, in m/s^2, is

(#M40027785) IIT-JEE question 2011 question Keep an EYE

A silver sphere of radius 1 cm and work function 4.7 eV is suspended from an insulating thread in freespace.
It is under continuous illumination of 200 nm wavelength light. As photoelectrons are emitted, the
sphere gets charged and acquires a potential. The maximum number of photoelectrons emitted from the
sphere is A ´ 10^z (where 1 < A < 10). The value of ‘Z’ is: Asked In IIT-JEE MAN (10 years ago); Unsolved; Is this Puzzle helpful? (4) (0) Submit Your Solution
