presbyopia.: it is a defect of vision due to which an old person cannot see the nearby object clearly due less power of accommodation of the eye...
current (I)=2A
time(t)=5 min
charge(Q)= ?
formula: I = Q/t...
now Q = It
calculation..
Q = 2×5
= 10coulomb
the charge is 10 coulomb..
HOPE IT WOULD HELP U BUDDY!!!!!!!!
