QAIPM-2011-Ph-1812: NEET 2011 Physics - Class 12 AIPM-2011-Ph-1812 Solution: The electric potential V at any point (x y z) all in metres in…
The electric potential V at any point (x y z) all in metres in space is given by V = volt. The electric field at the point (10 2) in volt/meter is 8 along negative X-axis 8 along positive X-axis 16 along negative X-axis 16 along positive X-axis
Multiple Choice Options
- A 5 cm
- B _ 10 cm
- C 20 cm
- D _ 30 cm
Step-by-Step Verified Solution
Here, v = +15 cm, u = +(15 � 5) = +10 cm
According to lens formula
1 v _ 1 u = 1 f
_ 1 15 _ 1 10 = 1 f
_ f = -30 cm
