First, find the center by using the midpoint formula for two pairs of points. Let's use (-2, 0) and (1, 1): h = (-2 + 1)/2 = -0.5 k = (0 + 1)/2 = 0.5 Now, calculate the radius using one of the points, say (3, -3): r² = (3 - (-0.5))² + (-3 - 0.5)² r² = (3.5)² + (-3.5)² r² = 12.25 + 12.25 r² = 24.5 Now, plug these values into the equation of the circle: (x - (-0.5))² + (y - 0.5)² = 24.5 Simplify: (x + 0.5)² + (y - 0.5)² = 24.5 So, the equation of the circle passing through the given points is (x + 0.5)² + (y - 0.5)² = 24.5. 🚀 Problem-Solving Approach: Practice more problems like this to enhance your skills in Circles.

Calculate the position and nature of the image formed by the mirror." 🌟 Explanation: To find the position and nature of the image formed by the concave mirror, you can use the mirror equation: 1/f = 1/v - 1/u Where: - f is the focal length of the mirror (given as -10 cm for a concave mirror) - v is the image distance (what we want to find) - u is the object distance (given as -15 cm, negative because the object is in front of the mirror) Now, plug in the values: 1/(-10) = 1/v - 1/(-15) Solve for 1/v: 1/v = 1/(-10) + 1/(-15) 1/v = (-3/30) + (-2/30) 1/v = -5/30 Now, find v: v = -30/5 v = -6 cm Since the image distance (v) is negative, the image is formed on the same side as the object, which is in front of the mirror. Therefore, it's a virtual image. 🚀 Problem-Solving Approach: Practice more problems like this to enhance your skills in Ray Optics. As you delve into the behavior of light and its interactions with mirrors, lenses, and optical instruments, you'll gain insights into how we perceive the world through the lens of physics! 🌈 #Physics #Optics #RayOptics #LightBehavior #ProblemSolving #ConquerJEE #TopicSpotlight
