SATHEE: Electrostatics Question 793

Electrostatics Question 793

Question: A ball of mass 1 g carrying a change $10^{- 8} C$ moves from a point A at potential 600 V to a point B at zero potential. The change in its K.E.

Options:

A) $- 6 \times 10^{- 6} e r g$

B) $- 6 \times 10^{- 6} J$

C) $6 \times 10^{- 6} J$

D) $6 \times 10^{- 6} e r g$

Show Answer

Answer:

Correct Answer: C

Solution:

[c] As work is done by the field, K.E. of the body increases by $K . E . = W = q (V_{A} - V_{B})$

$= 10^{- 8} (600 - 0) = 6 \times 10^{- 6} J$
