In order to aid students in fully grasping the idea, we (Web Tutors Point) have provided Electricity Class 10 Science MCQs Questions with Answers. Students can quickly respond to the MCQs from this chapter that will be asked in the exam by practising these MCQs.
A. 10J
B. 15J
C. 5J
D. 50J
Ans: A
Given,
Charge q = 0.5 C
Potential difference V = 20 Volts
We know that Work done W = qV
Therefore, W = 0.5 C × 20 V = 10J

(b) 14 V
(c) 7 V
(d) 3.5 V
