Learn To Converge Your Dreams with Durgam Vigyan Sansthana Institute. IIT JEE Physics MCQs IIT JEE Physics MCQs Below are multiple-choice physics questions with detailed solutions. Click "View Solution" to reveal the explanation. Question 1: A ball is thrown vertically upwards with a velocity of 20 m/s. What is the maximum height reached? (g = 9.8 m/s²) A) 10.2 m B) 15.3 m C) 20.4 m D) 25.5 m View Solution Solution: We use the equation of motion: v² = u² - 2gh At the maximum height, v = 0. Substituting the values: 0 = (20)² - 2(9.8)h 400 = 19.6h h = 400 / 19.6 h = 20.41 m Correct answer: C) 20.4 m Question 2: A block of mass 5 kg is pushed on a...
